You cannot nationally institute a change of heart. Besides that, you cannot possibly come up with a national program that could cater the needs of the people properly in the US -- a community could really take care of each other on a more intimate and real basis. It's not up to the government to be selfless for us -- it starts with the individual, then the community, then the nation. Not the other way around. It's very unrealistic, inefficient, and otherwise somewhat ignorant to expect it work that way...although the idea is nice, I'll admit.
Government isn't meant to make everyone happy. It's meant to take care of the decision-making process of and for the people, and make sure that things on the national level run smoothly. I'd much rather my government concern itself with quality in terms of laws and enforcement, etc, then a neighborly interest in the private lives of the people. A government is neither selfish nor selfless -- it's management, and it should stay that way. People should have access to happiness, but that doesn't mean it should be handed to them. And a government should clean up it's processes to make sure it runs smoothly before trying to conquer every humanitarian problem they see.
Well we already know medicare runs smoothly. That's why I support Medicare for all. All the other proposed ideas seem too messy. (imo)
And I also agree with Shai Gar though I'm hoping that a real healthcare bill gets passed as opposed to just increased regulation. But seeing as there's already several threads about healthcare, I'm not sure we should turn this into another one.
