What to do with taxes?

This article talks about the huge budget deficit and how it wont get any better unless taxes are increased or government expenses decrease significantly. One of the things that could be done would be increasing taxes for the rich. If this isn't done then the country is left with to options, increase taxes for everyone or cut government spending significantly. Unfortunately cutting government spending at this very moment would involve more factors in the decision than only economy related ones. So the country is left with the question of what to do with taxes, who to tax, and how much.
