No, it’s not a question of who pays for it but who benefits.
You could have universal health with zero additional spending by the US government, but all that administrative overhead is someone’s income.
Companies don't hesitate to lay people off when their jobs aren't needed. I don't see why these parasitic insurance companies need to stay in business.
No one benefits when there's a single player in an industry. When that single player also owns your taxes and military, its a risk we should at least avoid if at all possible.
