I can see how his "buy stock of evil companies" strategy might work, but typically you do that when the company is actually doing well, and not, say, when they're about to be curb stomped by the US government.
Also, his complaint about the "liberal media" is somewhat disingenuous, seeing as how he is part of the liberal media, what with the anti-corporate comic strip and the vegetarianism and the belief in affirmation and the whoa-hoy and the glaven.
