It doesn't.

My point is that where a person ends up in life (rich/poor, free/imprisoned) isn't always going to be based on what's "just".

Some people are lucky or unlucky and some people are hardworking or lazy. Bush is a lucky rich moron and others are hard working but broke.

It really pisses people off that guys like Bush are wealthy "unjustly" and they want to do something to even the playing field.

The fact remains that in general, people are responsible for where they have ended up in life, and there is a correlation between work ethic and income. I prefer not to punish those who IN GENERAL worked hard for the benefit of those who IN GENERAL weren't willing to do what it takes to improve their lot in life.
