Of course taxes should go up. If you want a low tax country, move to Central America.
The real question is 'in what proportion do the taxes go up?'
The American dream is that everyone has an opportunity. Iin difficult times, we all pull together, according to our ability to provide. The future of our country is everyone's future. Taxes (even high taxes) on multimillionaires/billionaires, doesn't affect their living standards. To who much is given, much is expected...someone said something like that once. He was right, in a perfect world.
We should aspire to a perfect world.
