Any chance you mean the ACA? (affordable care act). GP I think is talking about the AMA as a body that artificially constrains the supply of dr's (at least that is my guess as GP also mentions reducing limits on building hospitals).

IMO the GP is touching on removing regulatory burdens (more traditionally republican/conservative ideas) and adding in funding/care via medicare for all etc (democrat position). the combination of reducing/improving/simplifying regulatory burdens while increasing government spending seems to be a combination of ideas that hasn't been winning enough support. afaik, Ezra Klein in his book Abundance is one of the only voices trying to push this balance.

Yes, I meant to write ACA and that's what I (mis-)understood OP was talking about.
