Up, up, up, everything's costing more and more. According to the LA Times (via Ezra Klein):

Workers with job-based coverage for their families saw earnings rise 3% from 2001 to 2005, while their health insurance premium contribution increased 30%, according to the study by researchers at the State Health Access Data Assistance Center at the University of Minnesota.

What I can't understand is why Republicans think that doing nothing about this sort of thing will win them elections.
