Imagine a true free market healthcare system. Or just one step further than ours: no medicare. Imagine if every middle-aged middle or lower class American had to, as their parents age and require more healthcare than anyone can feasibly afford, choose: bankruptcy and permanent insurmountable debt, or watch your parents die knowing you chose not to stop it. What glorious freedom.
Medicare costs 17% of GDP and it has 44 million people. If you expanded medicare to every single person in america (10x), how much do you think the GDP cost would be then? And what do you think will be the prescription at that point?
Its also a ludicrous proposition to say that because its closer to free market, thats what makes it worse compared to socialized services. Its qualitatively different because it has tremendous regulation and rules. And the proposed solution is to add more regulation.
