In his Wall Street Journal op-ed today, House Budget Committee Chairman Paul Ryan (R-Wis.) said the Republican budget plan is focused on "saving Medicare."
Of course, in this context, this is intended to strip the word "save" of all meaning. Even the Wall Street Journal yesterday noted that the GOP proposal "would essentially end Medicare," which happens to be true.
Medicare is very easy to understand — it's a popular system of socialized, single-payer health care for seniors. Beneficiaries love it, and the system works pretty well. The House Republican scheme for Medicare is a little more complicated, but still pretty straightforward — the GOP intends to privatize it.
