You have to ask yourself two questions:

1) Why am I supporting a system that doesn't benefit me?
that sound pretty selfish but its more self interest. Do you think the rich/powerful don't game the system to their advantage? Their goals - no taxes or as little as possible/ be in a business that utilitizes the government - sell a prdt/svc to the tax system or swing tax subsidies / afterall the 'free market' isn't very profitable. Why are they making political contributions? Anyway, you're going to pay taxes, accept it and realize the answer to the two question:
2) What do I expect from government for my tax dollars? For nearly 200 years in this country the accepted mind frame was taxes were necessary to support the commons, they should be fair, and that the commons required taxes for their support.
