The tax cuts weren't related to our fall into depression. It just added to the blow of spending so much on wars and bailouts.
Even if you think the taxes need to be increased, there have to be like 50 other things we can do to benefit us more than whatever the increase would amount to. Unless we're talking about doubling taxes, I don't see how a small increase is going to be anything significant where it should be a priority at this time. In the long run, if we ever get our economy thriving again, then we can talk about taxes imo. There's so many more important things we should be worrying about that will lead to a more significant money gain.
