Now that the US healthcare industry has grown so rich and powerful it can lobby and win against any serious political efforts to either increase market competition or socialise healthcare. I.don't. Know how you could politically fix a system that is essentially "every man for himself" the incentive for corruption is far too high when payouts equal political power.
I doubt the US is subsidizing medical research as much as you'd think. The Pharmaceutical industry for example is very profitable compared to other industries. A socialised healthcare service would enable more competitive prices eating into industry profits for these products due to market scale like we see in the UK due to the buying power of the NHS.
"Among the largest 25 companies, annual average profit margin fluctuated between 15 and 20 percent. For comparison, the annual average profit margin across non-drug companies among the largest 500 globally fluctuated between 4 and 9 percent."
There are two problems with it. First, the US system is completely broken. It isn't a free market system, it's a worst of both worlds compromised hellscape. It's like comparing the USSR to Colombian druglords as evidence that communism is a great system. The USSR isn't great, Colombian druglords are just awful.
Second, the European systems rely on the US to fund world medical research through its high medical costs. We're subsidizing them. That makes us look bad, but they're the ones free riding on our system. And it's obviously not possible for the US to pay lower prices by doing the same thing and offloading its medical research costs onto the US. What we could do is make the EU pay more of the R&D somehow -- that could lower our costs for sure, or improve outcomes world-wide because there is more R&D. But what does that look like? Higher costs in Europe, right?
