I have smoked, so I'm going to give it a shot. *lights a cigarette*
People suck. People are going to do evil, corrupt things. People are going to abuse power. It's just human nature. The reason that capitalism exists is to avoid having one person or group being able to take control of the power in order to abuse it. Thus, anti-trust legislation and the like. I think that a mixed market economy is the best system, but I think that America's current system isn't mixed enough. I think we need to have more environmental legislation, more anti-price gouging legislation, more legislation that focuses on the ills of capitalism, and try to fix the problems that exist rather than drop kicking the whole works out the window, especially with no viable alternatives.
