from last year (when he was running for the nomination):

Just this week, Biden released his health plan. It calls for allowing all families to buy into the State Children’s Health Insurance Program, with sliding-scale premiums and co-pays based on income. He’d also allow people between 55 and 64 to buy into Medicare. And he’d allow the uninsured to buy into the insurance plan that covers federal employees, again on a sliding scale.

Maybe sheds some light on what he means when he talks about not creating another layer of bureaucracy. In other words, part of it already is (buying into [?!]) Medicare for more.

Doesn't make me love the dude, but makes me go "hmm".

certainly persuadeable.

One often-touted advantage of single-payer is the reduction in the bureaucratic overhead due to the elimination of the diverse, profit- (i.e. denial-) oriented claims processes of the private insurers. Something I don't think I've seen discussed is the bureaucracy that would be added by the so-called more feasible incremental solutions to universal health care. If you're really going to leave the private insurance business in place in such a way that it doesn't destroy the public plan, it will have to be regulated much more closely than it is now (see, for instance, how it's done in Germany). Regulation means bureaucracy, and we all hate bureaucracy, right?

Policy not party!
