Economists create their own worlds. We're like little gods with our artificial economics, wanting to see what happens.

The money is nice, but I am not in this game for the money.

The Chinese are saving like mad, but they are not getting a very good return on their savings.

Of all the thankless jobs that economists set for themselves when it comes to educating people about economics, the notion that society is better off if some industries are allowed to wither, their workers lose their jobs, and investors lose their capital - all in the name of the greater glory of globalization - surely ranks near the top.
