Just take a look at this chart from a WSJBlog post (http://blogs.wsj.com/wealth/2011/09/16/the-top-5-grabbed-most-of-the-americas-gains/)
- The rich are able to influence government disproportionately in their favor thereby increasing their wealth (tax policies that shift the burden to middle and lower income tax payers; deregulation of the financial sector). The Citizens United decision has amplified this factor.
- Being rich can lead to being given high income jobs regardless of merit (also large bonuses, golden parachutes, etc)
- Being rich means spending a smaller percentage of income on everyday necessities and being able to save/invest more
- Wealth can be inherited; the wealthy can afford to send their children to elite schools which lead to higher paying jobs for them
