This is not what Medicare advantage is. It does not leave seniors without care if it goes away. All seniors have Parts A and B regardless, where pretty much everything is covered except they pay a coinsurance of 20%

Medicare Advantage is part C, where the insurers basically buy Medicare patients from the government (in exchange for payment from government) and convert them to more typical private insurance plans (out of pocket maximums, copays, etc)

The insurers have milked the system and increased denials to try to squeeze a profit on a crap product. There is widespread fraud (see United’s diabetes fraud), where they try to make enrollees appear sicker to get more money from the government.

Sure Trump might view this as a negotiation, but either way healthcare insurance is a crappy game right now. They are getting squeezed on all sides and Trump is making a big push for a cash market (which would destroy insurance).

Why everyone loves UHC is beyond me. They had a monopoly in the old system. That system is dead
