I happen to agree with you in several respects. One thing that might be done is to flood the market with more M.D.'s. One thing that is being done is to shift a lot of work to nurse practitioners. We already have multi-tier health care, and that's OK with me - wealthy people get great medicine, poorer people get poor people clinics. Retail procedure costs and imagery diagnostics vary widely in cost from one region to another. Right now the cost of insurance is increasing double digits over last year because of uncertainty among insurance carriers that the ACA will continue to subsidize payments. Apparently that's not a zero-sum game, and total costs will hit less affluent people disproportionately. The Congressional response appears to be to allow high-deductible policies and higher pricing for those already sick.

The notion that the US can't afford decent health care for all is abhorrent to many liberals, while many conservatives want to shut down health care that requires subsidy.
