"Anonymous Internet commentator: Here's a bunch of common knowledge you can glean from any basic investment book. I'll omit the half that makes my argument look bad. Also, I can pretend to be someone who wouldn't naturally agree with you."
I don't know why the Internet eats this stuff up. It might be fun to go to conservative-monoculture forums and start posting: "I am an OWS organizer. I'm only here to appear more virtuous than my friends, and also to sleep with girls who have weird piercings and tattoos."
Politics articles in general are an utter black hole for intelligent discussion, but this one is also a portal into a completely new dimension of pointlessness.
