so the proposed bill is called medicare for all, but it would have to be explained how the govt can handle it because of the 100% govt run VA system and NOT medicare for which the expansion is named? i assume it's gonna be medicare but just everyone is eligible. and where as those over 62 have to buy supplemental insurance (or get it subsidized if they are poor enough), the cost of our supplemental insurance will come out of our paychecks and if you're poor enough subsidized by the govt.
as for how medicare is ran, they generally get good reviews from their "customers", better than the private insurance and they do a better job of cost control than private companies. they would be able to control costs even more if they were't hamstrung by congress who bows to pressure from the providers to raise how much medicare pays them. if they were truly negotiating without a leash and representing 100s of millions the health providers would pretty much have to agree with whatever the medicare negotiators feel is fair from a cost perspective while making sure people still want to be doctors and provide services. they could do the same with prescription drugs.
