Disincentives from Health Reform

Greg Mankiw writes:

Consider the following question, which is not about healthcare per se: Would you favor a substantial increase in marginal tax rates for millions of middle and upper income Americans to provide more resources for those toward the bottom of the economic ladder?

Your answer to this question cannot be determined by positive economics without adding in some normative judgments. But your answer should strongly influence your view of the health reform bill. The bill moves us closer to much of Western Europe by favoring equality and paying the price of reduced efficiency from much higher marginal tax rates.
