It used to be pretty easy to distinguish between the bourgeois world of capitalism and the bohemian counterculture. The bourgeois worked for corporations, wore gray, and went to church. The bohemians were artists and intellectuals. Bohemians championed the values of the liberated 1960s; the bourgeois were the enterprising yuppies of the 1980s. But now the bohemian and the bourgeois are all mixed up, as David Brooks explains in this brilliant description of upscale culture in America. It is hard to tell an espresso-sipping professor from a cappuccino-gulping banker.
