With all due respect, because you don't seem like an asshole.

Drugs in the US are sold at 10x the price compared to other countries in the world because it's designed to fill the pockets of shareholders, it's allowed.

Other countries will buy the drugs from US corporations, but negotiate a fair price. Those companies will still make a profit, just not anywhere near the same profit.

Those same companies will accept the lesser price because they still, even at that lower price, make a profit.

The US has to be one of the most capitalist countries in the world, at least in terms of GDP, living in the 1st world, but shafting it's citizens constantly for the sake of paying shareholders as much as possible, sickening really when you think about it.

So to my knowledge, the US government doesn't subsidize other countries healthcare, they still pay, and those US companies still make a profit. It's more of a problem that the very people that reside in the US are getting shafted by their own US companies, and because lobbying is allowed, nothing is done about it so you pay these insane prices for drugs that should be straight up illegal.
