"The exclusion of health insurance from federal tax now costs the government $248 billion annually. This tax subsidy has distorted America's healthcare marketplace.... Second, the employer exclusion encourages firms and individuals to seek overly generous insurance benefits. Subsidies cause people to consume more of something. Since a dollar of untaxed health benefits is worth more than a dollar of taxed wages, workers understandably opt for more health benefits.... Obamacare failed to address these problems."
