The problem is that most people in the middle class dream of being rich or having their business really take off. Therefore, they worry about being in a high tax bracket when they're not (and probably won't be).
Other people don't want to pay for all the services of the freeloaders and unemployed. And if the government provides the same level of care/services for all, what incentive is there to work?
The third thing is why should the rich have to pay for all the government programs?
