Shifting an even GREATER burden on the upper income brackets is not a good idea. The top 50% already pay 95% of all income taxes! Additionally, those with greater incomes are typically the ones who create jobs, wealth, and opportunities. Since you're already taking away the corporate welfare, you hit those same (already over-taxed) producers with yet another tax increase. This does NOT spur economic growth. This furthers the division between the classes (those who are taxed HEAVILY, and those who are not taxed at all... not exactly equal representation). This also brings us closer to the nightmare reality that those who pay no taxes will make up the voting majority, and will out-vote those who do pay the taxes. We should be running away from the Marxist model, not promoting it.
Your prioritization includes education and protecting social security. Despite my career choice, I think that the federal government should adhere to the Constitution, and leave education to the state and local levels of government. Finally, the social security Ponzi scheme doesn't need protecting, it needs an absolute overhaul.
I'm think that the majority of conservatives would agree with those points.
