lol, as someone who gets free healthcare in the UK thats really amusing. Why not just make it a tax for the minimum requirement? (you could even make it dependent on income although possibly thats too shocking)
It is very politically difficult to raise taxes or introduce new taxes anywhere in the USA, even Massachusetts. Also many people in the USA are skeptical about socialized health care. The USA's system is definitely broken in some ways but it is not clear at all that the systems of other counties are not also broken in different ways.
