You’re confusing capital and operating costs. Once you’ve developed the drug, selling everywhere you can makes sense. When considering whether to develop a drug or invest in something else, America’s biotech market absolutely turns keys. (But not as uniquely as we think. Europe has a thriving R&D market, it’s just directly subsidised.)
America subsidizes these drugs for the rest of the world, which does not pay its fair share into R&D costs. If we’re to fix our healthcare system, this kind of thing can’t continue.
Any negative response to that must suppose that everyone else would just give up on trying to advance drug R&D if the US stopped unilaterally self-sacrificing to subsidize it for the entire world... and when you lay it out like that, it seems like that must not actually be what's going on in the first place, because why the hell would we be do that, for that reason? So, very probably, we aren't, and further, if we are we should definitely stop.
I doubt governments elsewhere are itching to increase their healthcare spending even more. Realistically speaking the actual result will be cost cutting from pharma companies, mostly in the form of lower R&D spending for new drugs.
You didn't provide any context of why you think that could be the case or the mechanism through the alleged subsidies happen.
You literally have to get fucked or the world get fucked harder and drags you down with them. Same reason why NATO and the farm bill are good for America.
The greatest trick from the wealthy is to not just exploit you to get it, but to destroy any possibility of resistance to them. Even trying to resist does nothing but harms the under class even more than if you simply accept it.
“If you want a picture of the future, imagine a boot stamping on a human face—forever.“ - George Orwell, a communist/socialist
Edit: To the guy who claimed Orwell wasn't a communist, the POUM who he fought for in the Spanish Civil war was communist (https://en.wikipedia.org/wiki/POUM) and according to the soviet union was specifically trotskyist. If you fight for them you are a communist, even if and especially if you claim you weren't later in life.
He actually said "As far as my purely personal preferences went I would have liked to join the Anarchists." After the Stalinists illegalized the POUM, killed and tortured Orwell's friends and tried to kill him, forcing him flee Spain, his view on Communism grew ever more dim, and after that he grew more strongly anti-Communist than his earlier anti-Fascism.
Later
"Orwell was a communist even if he said otherwise" is a telling argument.
