I read this post about free spaces some time ago. I think the more free spaces you have[energy level,intelligence, likability] the easier it is to look down on people with fewer free spaces. You see people crashing into invisible walls that you move through easily... It's easier to just say they are lazy, terrible, failures. If only they had worked harder, were better people, they would be able to tear down those walls that don't affect you. That's the tyranny of our individualist ideology. Every stumble is a moral failure.
