Walter E. Williams: Inequalities everywhere in earnings differences

“President Obama Vows Zero Tolerance on Gender Wage Gap,” read one headline. Another read, “Women Still Earned 77 Cents On Men’s Dollar In 2012.” It’s presumed that big, greedy corporations are responsible for what is seen as wage injustice. Before discussing the “unjust” wage differences between men and women, let’s acknowledge an even greater injustice — which no one seems to care about — age injustice.

Trudy Rubin: Exhibit presents lessons

At a time when sectarian wars are on the rise, a fascinating exhibit at the Free Library of Philadelphia reminds us that people aren’t born with these visceral hatreds, but are taught them.

Froma Harrop: Ask not what your cat can do for you

Abig-selling book, Cat Sense: How the New Feline Science Can Make You a Better Friend to Your Pet, helps cat lovers understand what is going on in the hearts and brains of their kitties. Sadly, not nearly so much as they thought and hoped.

Linda Chavez: Policies at Dartmouth set stage for trouble

Dartmouth College has a problem. Protestors occupied the president’s office at the Ivy League school a couple of weeks ago and demanded more “womyn or people of color” faculty, coverage of sex-change operations on the student health plan, and “gender-neutral bathrooms,” among other things. Now Dartmouth President Philip J. Hanlon has responded with a call “to end the extreme behaviors that are in conflict with our mission.”

Leonard Pitts: Sports team owner unveils new flimflam

Twenty-four dollars. That, supposedly, was the price Gov. Peter Minuit paid American Indians for the island of Manhattan in 1625. It’s a tale historians find suspect.

Steve Chapman: Harmless drones get flak from feds

In March 2012, volunteers spent four days looking for a 2-year-old boy who wandered away from his home outside Houston. They found him only after volunteers reviewing images captured by a drone-mounted aerial camera saw a flash of red in a pond that had already been searched. It turned out to be a shirt worn by the child, who had drowned.

Bob Bland: Experience the wonder of Easter today

It had been a tragedy-filled weekend. We spent yesterday, the Sabbath, huddled together in fear for our lives while grieving the execution of Jesus on trumped-up charges. Bewildered and emotionally empty, I kept recounting the events of the past three years and wondering what it all meant.

Thomas Sowell: Chris Stone recalled as unique man

Black journalist Chuck Stone was one of those people whose passing makes us think, “We shall not see his like again.”

Jonah Goldberg: Krugman, Klein show their bias

“If all you have is a hammer,” the old saying goes, “everything looks like a nail.” Left unsaid is the fact that the real problem isn’t the possession of a hammer, but the certitude that all you need is the hammer. In other words, it’s a failure of the imagination — which is a kind of arrogance — that’s really to blame. “I’ve got my hammer, and that’s all I need. Besides, have you ever seen a problem that didn’t look like a nail?”

Clarence Page: Could LBJ pass act now?

Fifty years later, it’s hard to imagine the enactment of the Civil Rights Act by today’s polarized Congress. Maybe, as the old saying goes, today’s fighting is so vicious because the stakes are so small.

Kathleen Parker: Colbert no threat to heartland

WASHINGTON — In selecting Stephen Colbert to replace David Letterman as host of the Late Show, CBS has waged war on America’s heartland — or so proclaims that Palm Beach font of heartland mirth, Rush Limbaugh.

Froma Harrop: Shed light on spending

Foes of Obamacare often frame such health reforms as “redistribution” schemes. They take money from hardworking Americans and give it to the presumably undeserving.

Walter E. Williams: Equality in student discipline a bad idea

George Leef, director of research for the North Carolina-based John William Pope Center for Higher Education Policy, authored a Forbes op-ed article titled “Obama Administration Takes Groupthink To Absurd Lengths.”

Linda Chavez: Jeb Bush should try Reagan’s methods

Agree with him or not, you have to respect Jeb Bush’s honesty. On two issues, immigration and a common core in education, Bush recently went on record stating positions at odds with some powerful activists in his own party.

Mary Sanchez: Mullen: Put returning soldiers to work

How do you recognize a military veteran? Really see them, once they’re out of military fatigues. No boots and camouflage. After the homecoming is over, with its flags and patriotic speeches and TV cameras and families weeping in relief.

Steve Chapman: Legalizing marijuana a dilemma for Democrats

Legalizing marijuana is an issue made to order for the Democratic Party. A majority of Americans now supports the idea, and so do two out of three Democrats. Two states have done it, and several more may vote on it in 2016.

Trudy Rubin: Turkish fight has U.S. angle

Turkey’s prime minister, Recep Tayyip Erdogan, has declared war on “the man in Pennsylvania.” This bizarre battle pits Erdogan against an elderly Turkish scholar of Islam named Fethullah Gulen, who lives in self-imposed exile in Saylorsburg, Pa., on a 26-acre compound called the Golden Generation Worship and Retreat Center.

Clarence Page: Culture matters in effort to become high achiever

Congratulations, Kwasi Enin. You’re a 17-year-old Long Island high school student who applied to all eight of the nation’s elite Ivy League universities — and received acceptance letters from all of them!

Jonah Goldberg: Climate activists uncaged

Finally, someone has come up with a way to settle the debate over climate change: Put the people on the wrong side of the argument in cages.

Froma Harrop: America and Canada: together at last?

What country do Americans overwhelmingly like the most? Canada. What country do Canadians pretty much like the most? America.

Kathleen Parker: No offense meant to Southerners with remark

WASHINGTON — After writing close to 3,000 columns, I’ve learned that people sometimes read what they’re looking for, often as a result of a headline, rather than what I wrote. Same words, different prisms.

Leonard Pitts: Again, Christianity the last to get it right

Eleven years ago, Richard Stearns went to Washington. Stearns — president of World Vision, the billion-dollar Christian relief organization — joined other faith leaders in lobbying Congress to spend $15 billion combating AIDS in Africa and the Caribbean. He acknowledged he and his fellow evangelicals were late to the fight against this pandemic and explained their tardiness with remarkable candor.

Thomas Sowell: Left wing depicts its interests as crusade

The recent Supreme Court decision over-ruling some Federal Election Commission restrictions on political campaign contributions has provoked angry reactions on the left.

Jane Nelson: State must improve ways to protect children

Walt Disney once said children are our greatest natural resource — a notion that conveys both love for children as well as the belief that they must be protected.

Walter E. Williams: Elites use government to control the people

The documentary Engineering Evil was recently shown on the Military History channel. It’s a story of Nazi Germany’s murder campaign before and during World War II.

Susan Estrich: Abortion fight continues 40 years after ruling

It has been more than 40 years since the United States Supreme Court held in Roe v. Wade that a woman, in consultation with her physician, has the right to decide whether to have a child in the early months of pregnancy.

Steve Chapman: Campaign donation ruling no big deal

The Supreme Court decision killing limits on total donations to political candidates means billionaires will be running amok. Casino magnate Sheldon Adelson can lay out astronomical sums to help Republicans. Oilmen Charles and David Koch can see him and raise him. Former New York Mayor Michael Bloomberg can burn through his fortune like a blowtorch.

Clarence Page: Memo to GOP: Poverty isn’t just about race

Why does so much of our talk about race and poverty leave us Americans spinning our wheels? One big reason is etiquette. What is said often matters less than who says it.

Linda Chavez: Race not a factor in Fort Hood shooting

I like Megyn Kelly. The Fox News anchor is smart, lively and gorgeous. But she’s managed to walk right into a controversy over race and ethnicity, and it’s not the first time.

Froma Harrop: Democrats shouldn’t run away from Obamacare

The ruckus around the Affordable Care Act rollout has been loud, and Republicans are beefing up the amp to rally voters this November. Democrats, meanwhile, are reverting to bad old habits by using the wind machine as an accurate gauge of public feelings.

Jonah Goldberg: Obama’s stand-up routine laughable

President Obama was doing his favorite thing recently: talking to crowds of adoring young people who already agree with him while acting like he persuaded them about something.

Mary Sanchez: Home from war, our soldiers continue to die

March ended with this uplifting news: For the first time in seven years, no U.S. soldiers died that month in combat. Not one.

Kathleen Parker: Democrats get more desperate

WASHINGTON — H.L. Mencken gets a workout in election years when voters are reminded by pundits of the curmudgeon’s observation that no one ever went broke underestimating the intelligence of the American public.

Doyle McManus: Evangelicals change ways

Only a decade ago, Christian social conservatives were a commanding force in American politics. They helped elect one of their own, George W. Bush, to two terms. They were a cornerstone of a GOP coalition that appeared to hold a permanent electoral majority. But today, the movement has lost its momentum — in part because one of its assets has become a liability.

Steve Chapman: Victory can be a recipe for defeat

Lawyers for Hobby Lobby recently urged the Supreme Court to let companies opt out of certain health insurance rules for religious reasons, and they have a good chance of success. If employers are allowed to refuse to provide coverage that pays for certain types of contraception, it will be a big victory for religious conservatives. Or will it?

Leonard Pitts: No excuses for bias

What excuses will they make this time? Meaning that cadre of letters-to-the-editor writers and conservative pundits who so reliably say such stupid things whenever the subject is race.

Thomas Sowell: U.S. foreign policy does more harm than good

Japan recently turned over to the United States enough weapons-grade nuclear material to make dozens of nuclear bombs.

Clarence Page: Satire requires context

One of the unwritten but widely respected rules of satire is that somehow, somewhere, someone simply isn’t going to get the joke. And if they don’t get the joke, you get taken seriously about something you don’t really believe.

Walter E. Williams: Liberals unrealistic on issues of equality

There are several race and sex issues that need addressing. Let’s look at a few of them with an ear to these questions: Should we insist upon equal treatment of people by race and sex or tolerate differences in treatment? And just how equal are people by race and sex in the first place?

Froma Harrop: U.S. has two-track minds on security, privacy

The first shocking headlines after Malaysia Airlines Flight 370 disappeared revealed that two men had boarded with stolen passports. “Stark evidence of security gap,” blared The Christian Science Monitor.

Linda Chavez: Help college players get just deserts

A controversial ruling by the regional director of the National Labor Relations Board recently gives college football players the right to form a union. At issue was whether scholarship players should be considered employees of the university, in this case Northwestern University. NLRB Regional director Peter Ohr ruled that the players are athletes first and students second.

Mary Sanchez: End access to guns by dangerously mentally ill

The federal government believed Colby Sue Weathers was a paranoid schizophrenic. It had information that she was delusional and suicidal, unable to work and therefore eligible for Medicaid and disability benefits.

Trudy Rubin: Send strong message to Russia

George Santayana famously said, “Those who forget the past are condemned to repeat it.” But when it comes to Russia and Ukraine, Western leaders can’t seem to decide which century’s lessons they should take to heart.

Susan Estrich: Pure evil makes world tough place to live in

I admit it. I have been obsessed with the plane. Most of the stories I’ve read offered no new information, but I read them anyway.In a way, I suppose, it is a relief to know that the 777, long considered to be an extremely safe plane, was not brought down by some as yet unknown engineering defect.

Jonah Goldberg: Shine light on liberals’ shady side

Leland Yee, a Democratic state senator and candidate for secretary of state in California, has been a longtime champion of gun control. Recently, he was arrested on numerous charges, including conspiracy to deal firearms without a license and conspiracy to illegally transport firearms.

Leonard Pitts: Fred Phelps wasted his gift of long life

And what shall we say now that the monster has died? His estranged sons Mark and Nate told the world recently that their 84-year old father, Fred Phelps, was in the care of a hospice and “on the edge of death.” Later, he went over the edge.

Steve Chapman: President continues to meddle with pay

If you take an economics course, you may learn about the different events that can cause an increase in workers’ pay. The demand for the product a worker makes may rise, causing the demand for workers to go up. The supply of workers may decline, causing employers to bid up wages to keep the ones they have.

Clarence Page: Cable TV enters news candyland over lost jet

If television is chewing gun for the eyes, as an old saying goes, the Malaysia Airlines mystery plane has turned cable television news into candy for the ears.

Kathleen Parker: Putin still living in the past

WASHINGTON — “Once an agent, always an agent.”
