Cato has a great article. Here is a great quote:

Today, anti-corporatists want corporations to put some vague notion of altruism ahead of profit, innovation, and investment. That’s terribly shortsighted. Capitalism has proven to be the best way of creating wealth because it trusts that the collective wisdom millions of people voluntarily engaging in millions of mutually-beneficial transactions every day is the best way for an economy to allocate its resources.

Combining mutually-beneficial transactions and the freedom to do so is the only real way to create wealth.  Its our job to spread the good word, to beat back the lies of the idealist utopia-ists.
