If things are bad enough people want change. I don't think it is ever possible to change a complex system like a whole society exactly you want it to be. But sometimes you just want something new.

As for not raising taxes being the most important issue: I kinda find it rather strange that people seem to have no problem at all to give their money to some jackass bankers in the form of mortgages or interest on credits. Money which is obviously spent on exorbitant boni and even more stupid things.
But at the same time the same people have a tremendous problem giving money to the government, which provides them with schools, streets, infrastructure, safety and much more (i'm not saying that some of the taxes are spent foolishly, but most istn't)
