Interesting studdy done by Larry M. Bartels from Princeton University (from 2005).

His findings? That based on voting patterns Congress clearly favors the wealthiest members of society.
He finds that the poor by foor are least represented. The next most represented is the middle class. Then the highest level of representation (bill favoring) is the upper class.
He then does a comparison of bills that will favor one group to the detriment of another.
Once again the lower income group always loses out.
The middle class of course always loses out to the upper class.
So...based on Senate voting patterns wealth by far determines what stuff you get from government.
Thoughts?
I know for some this is just providing the data that supports what most people already know but the degree in which it takes place is pretty astounding.
