[W]hen I think of New York city abstractly, I think of a city that doesn't work. Taxes are high, there are too many crowds, people are pushy and unfriendly, etc. Then, when I actually experience New York, I see how well it works. People are trying to give me what I want, at a fairly low price. The immigrants I run into--and there have been many over the last two days--don't seem to have come here for welfare but for opportunity to get wealthier. And people are friendly.
Why are people friendly? Partly because I love people and I'm friendly to them. But also partly because they are paid to be friendly; they do better by being friendly to customers.
