In a post over at inclusionist, Shawn Fremstad makes a crucial point about federal health care spending.
In fact, the 2nd biggest health care entitlement isn't Medicaid, it's the $200+ billion tax break for employer-sponsored health insurance. The health insurance tax break costs around $30 billion more than Medicaid and, if my recollection is correct, is increasing at a faster rate than either Medicaid or Medicare. It's also, unlike Medicare or Medicaid, a regressive tax subsidy that provides more benefits for the wealthy.
