The best escalator to opportunity in America is education.

I took a gap year myself after high school and worked on a farm near Lyon, France. I stayed with the Vallet family, picked and packed fruit, and discovered that red wine can be a breakfast drink. That led to further travel as a university student.

You no more have the right to risk others by failing to vaccinate than you do by sending your child to school with a hunting knife. Vaccination isn't a private choice but a civic obligation.

A basic element of the American dream is equal access to education as the lubricant of social and economic mobility.

Just a little help, a small security force, a bit of food, can save lives.

I do think that humanitarians and journalists alike have focused on all the things that go wrong, and that they sometimes leave the perception in the public that the war on poverty has been lost. That Africa is just a bottomless pit of despair. When, in fact, really the opposite is true on both fronts.

Random violence is incredibly infectious.

In America, we have subsidized private jets, big banks and hedge fund managers. Wouldn't it make more sense to subsidize kids?

Sure, food stamps are occasionally misused, but anyone familiar with business knows that the abuse of food subsidies is far greater in the corporate suite. Every time an executive wines and dines a hot date on the corporate dime, the average taxpayer helps foot the bill.

Every year 3.1 million Indian children die before the age of 5, mostly from diseases of poverty like diarrhea.

Sex and gender are such befuddling mysteries even for those of us who are in the mainstream that you'd think we'd be wary of being judgmental. Yet much of society clings to a view that gender is completely binary, when, in fact, there's overwhelming evidence of a continuum.

I wouldn't want everybody to be an art or literature major, but the world would be poorer - figuratively, anyway - if we were all coding software or running companies. We also want musicians to awaken our souls, writers to lead us into fictional lands, and philosophers to help us exercise our minds and engage the world.

Numeracy isn't a sign of geekiness, but a basic requirement for intelligent discussions of public policy.

Too often, wealthy people born on third base blithely criticize the poor for failing to hit home runs. The advantaged sometimes perceive empathy as a sign of muddle-headed weakness rather than as a marker of civilization.

Seniors vote, and that is why we have, you know, Medicare since the 1960s for seniors, and we didn't have a national healthcare program for children, even though it's a lot more cost-effective to deal with children than with seniors.

Most moms and dads, they want to be good moms and dads. But it's an incredibly hard job when you are stressed out, when you are poor, when your life is in chaos. And giving them some of the tools to be better parents, to whittle away at that parenting gap, gives those kids a much better starting point in life.

One of the things you learn as a journalist is that when there's no accountability, we humans are capable of tremendous avarice and venality. That's true of union bosses - and of corporate tycoons. Unions, even flawed ones, can provide checks and balances for flawed corporations.

Abortion politics have distracted all sides from what is really essential: a major aid campaign to improve midwifery, prenatal care and emergency obstetric services in poor countries.

The ice bucket challenge went viral in 2014, partly because it was so much fun to watch videos of celebrities or friends dumping ice water on their heads. Videos of people in the challenge have been watched more than 10 billion times on Facebook - more than once per person on the planet.

One of my frustrations is that we in society generally have this bifurcation in how we see the world. That's probably a little less true with business audiences, but in general, there tends to be this view that for-profit companies are greedy, and nonprofits are noble. It's absolutely more complicated than that.

I think humanitarians really feel very awkward and embarrassed about marketing, but it really doesn't matter whether a shampoo gets better marketing. It does matter when a famine or a huge crisis is - oh - well, I hate to use the word 'marketed' better but, you know, is publicized in a way that will be more effective.

When the poor know that their children will survive, when they educate their daughters, when they access family planning, they have fewer children.

Remember that disadvantage is less about income than environment. The best metrics of child poverty aren't monetary, but rather how often a child is read to or hugged.

Too often, I believe, liberals deny that poverty is linked to bad choices.

One of the aims of higher education is to broaden perspectives, and what better way than by a home stay in a really different country, like Bangladesh or Senegal? Time abroad also leaves one more aware of the complex prism of suspicion through which the United States is often viewed.

There are other issues I have felt more emotionally connected to, like China, where I lived and worked for some time. I was living there when Tiananmen Square erupted.

Most of the villagers were hiding in the bush, where they were dying from bad water, malaria and malnutrition.

Beware of generalizations about any faith because they sometimes amount to the religious equivalent of racial profiling. Hinduism contained both Gandhi and the fanatic who assassinated him.

Every high school and college graduate in America should, I think, have some familiarity with statistics, economics and a foreign language such as Spanish. Religion may not be as indispensable, but the humanities should be a part of our repertory. They may not enrich our wallets, but they do enrich our lives. They civilize us. They provide context.

Most of the time in the 21st century, we dominate our surroundings: We tweak the thermostat, and the temperature falls one degree. We push a button, and Taylor Swift sings for us. It's the opposite in the wilderness, which teaches us constantly that we are not lords of the universe but rather building blocks of it.

Zimbabwe has far fewer tourists than South Africa or Kenya, and there's less crime as well.

Things that happen every day are, frankly, what we in the news business aren't good at covering because there is no one day in which they are news.

Utah may well be the most cosmopolitan state in America. Vast numbers of young Mormons - increasingly women as well as men - spend a couple of years abroad as missionaries and return jabbering in Thai or Portuguese and bearing a wealth of international experience.

Worrying about bills, food, or other problems leaves less capacity to think ahead or to exert self-discipline. So, poverty imposes a mental tax.

The world spends $40 billion a year on pet food.

I think it's dangerous to be optimistic. Things could go terribly wrong virtually overnight.

I can't help thinking that if the American West were discovered today, the most glorious bits would be sold off to the highest bidder. Yosemite might be nothing but weekend homes for Internet tycoons.

The one public system in which America goes out of its way to provide services to African-Americans is prison.

We journalists are a bit like vultures, feasting on war, scandal and disaster. Turn on the news, and you see Syrian refugees, Volkswagen corruption, dysfunctional government. Yet that reflects a selection bias in how we report the news: We cover planes that crash, not planes that take off.

The north of the Central African Republic is now a war zone, with rival armed bands burning villages, kidnapping children, robbing travelers and killing people with impunity.

What use could the humanities be in a digital age? University students focusing on the humanities may end up, at least in their parents' nightmares, as dog-walkers for those majoring in computer science. But, for me, the humanities are not only relevant but also give us a toolbox to think seriously about ourselves and the world.

A few countries like Sri Lanka and Honduras have led the way in slashing maternal mortality.

However imperfectly, subsidies for the poor do actually reduce hunger, ease suffering and create opportunity, while subsidies for the rich result in more private jets and yachts. Would we rather subsidize opportunity or yachts? Which kind of subsidies deserve more scrutiny?

The caricature of Islam as a violent and intolerant religion is horrendously incomplete. Remember that those standing up to Muslim fanatics are mostly Muslims.

It really is quite remarkable that Darfur has become a household name. I am gratified that's the case.

I have a one-question language test that people who have lived abroad do better on than those who studied in a classroom. Try my test yourself: In a foreign language you've studied, how do you say 'doorknob'?

Literature seems to offer lessons in human nature that help us decode the world around us and be better friends.

There are very few things I've done just twice in my life, 40 years apart, and one is to backpack on the Pacific Crest Trail across the California/Oregon border.

Perhaps no country in Latin America is more picturesque than Bolivia, and the most memorable Bolivian city may be Potosi.

If President Bush is serious about genocide, an immediate priority is to stop the cancer of Darfur from spreading further, which means working with France to shore up Chad and the Central African Republic.
