Extra spending on health care is not actually required (even though america could afford it). Americans spent more per capita on health care than anyone else already. American health spending is extremely inefficient, with parasites like for-profit insurance (whose profits and much of their revenue are literally just inefficiency in the system) embedded at every layer. The problem is that allowing it to get to this state means many of these bad actors will gladly spend hundreds of millions on politicians and ads to defend the billions they make, and American voters are easily confused.

If you call profits a bad thing too many times you get called a communist or whatever even though in this case it’s objectively true. The shooting of that parasite CEO should have brought this into focus - that worthless person profited directly from making people’s health care expenditures less efficient (and also from the corresponding human suffering in case anyone cares).

the US already allocates $1.5 trillion for direct healthcare spending

Every single time someone brings up anything about cost and the government, ask them how much money the DoD loses every year. Every single time.
