That’s a weird framing. One party would introduce single-payer in a heartbeat, the other demonises it. Let’s not pretend we’re talking about “government” as a whole here, rather than the GOP
It’s a weird framing when the only way you propose to lower costs is through a revolutionary change which sees major political barriers to actually happening.
How about lowering costs anyway? I assure you, there are real and meaningful ways. Start by removing anticompetitive Certificate of Need laws, at the state level.
And for prescription drugs, tie the prices to what some other countries pay.
Some of the solutions are really easy but it’s hard to get done when some politicians are paid off, some want the system to fail so they can do single payer, and some are vehemently anti regulation.
Something more drastic would be making all health insurance plans be high deductible (as in, make it insurance again), and ensure that prices are up front and transparent. You’d see prices plummet relatively quickly.
