“The Christian right, which trumpets the theme of family values, damns contemporary culture for undermining older traditions. Yet many individuals from this camp are not concerned first and foremost about family values per se. Family is a codeword for constraint; families and family values place constraints on individuals more effectively than any other institution, including government. The Christian right seeks a society in which all are constrained; they reject big government for failing at constraint, and for undermining those institutions, like the family, that have a chance at succeeding.”

“For the U.S., I think we should have a carbon tax, for environmental reasons.”

“The way to make the world a better place, through your eating, is simply to eat a bit less meat. Local is sometimes good, sometimes bad. But even when it's good, its environmental impact is relatively small compared to other possible improvements.”

“I think people who are not rich can be extremely happy. And I think the chances to be happy in this new world - with many more opportunities to be creative, to be online, to educate yourself - there'll be a lot more chances to be happy. It's not to say everyone will take them, but there will be a lot of new paths to opportunity.”

“Often, economists spend their energies squabbling with one another, but arguably the more important contrast is between our broadly liberal economic worldview and the various alternatives - common around the globe - that postulate natural hierarchies of religion, ethnicity, caste and gender, often enforced by law and strict custom.”

“A lot of local food is very tasty. I'm very happy to eat it. I just don't think it's the same thing as saving the world.”

“Vietnamese food has probably been saved from the mass market because most people never master the sauces and condiments that must be added to the food, at the table, for its glories to become apparent. It's too much trouble, and a lot of people don't like asking for help, especially if the interaction involves some linguistic awkwardness.”

“If we want to improve American food and make it much cheaper, we should deregulate the food trucks and the other street vendors, provided they meet certain sanitation standards. Many cities have already moved down this path, and people are not keeling over with salmonella.”

“I've been a foodie most of my life. I started when I lived for a year in Germany in my early 20s, and here was this new food environment, and I decided I needed to make sense of it. And I found it was the rules of economics that do the best job. Food is a capitalist product of supply and demand.”

“We're seeing an enormous amount of global upward mobility that's quite rapid and quite sudden, and undiscovered individuals have a chance - using the Internet, using computers - to prove themselves very quickly. So I think the mobility story will be a quite complicated one.”

“When humans team up with computers to play chess, the humans who do best are not necessarily the strongest players. They're the ones who are modest and who know when to listen to the computer. Often, what the human adds is knowledge of when the computer needs to look more deeply.”
