I'm concerned about Mitt Romney's (and Paul Ryan's) plans for a federal role in health care, as costs will rise. Romney pledged not to increase tax rates, in contrast to President Barack Obama's urging Congress to increase them on the highest-income Americans. If a President Romney and a Republican-dominated Congress repeal the Affordable Care Act, Romney says he will keep parts people like. Which are they, and which will he cut? To balance the budget, Romney and Republicans promise to cut federal aid to states for health care as well as education, environmental protection and other services. States that have low or no income taxes will have to raise them, or keep the same poor to mediocre levels of social support they provide even with federal help. Or will state and local property taxes, sales taxes and usage fees rise even higher? These taxes are regressive, harder on people with less income.
