Raising income taxes on private citizens is a bad idea. In the first place income tax has never been constitutional, except for those that manufactured and sold alcohol illegally. Even today if a person has enough wherewithal and legal support to stand up against the IRS, it is possible (and expensive) to win the constitutional right to not pay income tax so long as you do not start making or selling alcohol illegally. Let's make the tax brackets more reasonable for people to keep more money. And then these people will start businesses and invest in the economy to produce growth and more than enough money to pay off the national debt.
