Do we ever envision a time when taxes shouldn't go up on everyone? I don't. The tax rates were perfectly fine under Clinton, why are they bad now?
Taxes definitely need to go up on the rich, capital gains must go up, corporate minimum must come back and I'd love to see a Wall Street transaction tax but I don't see why working class people shouldn't also pay a little more. Save the very poorest from it but everyone should be willing to pay a little more for the greater good.
