As much as I want to, I just can't get behind communism. I can't.
People are incapable of truly being selfless, being without greed. I'm not saying you cannot achieve this yourself, but there will always be someone who will refuse to do so. They like money and what it brings them. And the chances of this person being a government official are even higher as he now has power, and with power can create so many opportunities for greed that it frightens me too much to allow the country to go down that road. Great on paper, just can't really work in the real world. Every communist attempt has shown this.
Meanwhile, capitalism, or rather, American capitalism, has become so estranged from it's original purpose that I can't back it any more.
