Democrats asked CBO to lay out some parameters of how to set up single-payer, hoping to elude analysis of any one bill in Congress. The latter would carry political accountability—and a price tag. Instead CBO walks through “key design components and considerations” in a report that aims to bore and deploys the word “could” 209 times. Yet even this limited analysis is instructive about the “major undertaking” of single payer, as CBO puts it in hilarious understatement. CBO acknowledges, for example, that a transition that includes moving 160 million people from employer-sponsored coverage to single payer would be “complicated, challenging, and potentially disruptive” to health care and the economy. You don’t say.
