Congressional leaders are weighing their options for moving the Senate-passed health care overhaul through the House. That legislation would have the undesirable effect of discouraging low-wage workers from climbing the economic ladder. A new Cato Institute study by Michael F. Cannon finds that implicit tax rates would often exceed 100 percent for low-wage workers, which could trap millions of Americans in low-wage jobs. Cannon also finds that the Senate bill creates incentives as large as $8,000 per year for people to purchase health insurance only when they are sick.
