The appeal to vulgarity is a tired cliche of social critique. At this point, no one can make a fresh point about it. Now it's just exploitation of the weak.

At this point, saying that an economic activity is an exploitation of the weak is redundant.

More like a critique of the distorted "keynesianism" governments around the world seem to love.

Isn't it interesting how satirical humor often serves as a kind of rorschach test?

I remember reading something about both conservatives and liberals thinking Colbert's character was making fun of the other.

That's satire, almost by definition (as opposed to other kinds of humor).
