Public healthcare is excellent, but I'm not sure if it will ever work in the states because it's not beneficial to so many influential parties, and we all know that politics in the US is all about the lobbying of these same parties; individuals and companies that benefit from privatized healthcare, for example the insurance industry.
The lobbying is very efficient. Opinions are turning against the healthcare reform with the support of the beneficiary parties. So is the loyal herd of sheeps that is the american public, which gets its "opinions" mostly from right wing media supported by those same corporate lobbyists that affect the political parties too.
All political agenda aside, who in their right mind would be against an effective public healthcare reform? Any country that wishes to one day call themselves civilized needs to provide their citizens with the basic necessities of life; food, water, shelter, health. That's just how it is. If you throw the sick and homeless to the streets it'll just rot your country and eventually turn it to a 3rd world hellhole. I guess another option would be to just execute them like the nazis did but there are ethical reasons why that can't be done.
"But I don't want to spend my precious money to support some lazy bums who could just as well support themselves if they were not freeriders" - Yeah nobody wants to spend their hard earned money but it has to be done. Often the poor people have a reason other than plain lazyness, they may be too sick to work physically or mentally, there might be no work because of the local economical situation, or yeah they might just be lazy and want to live for free. The amount you pay in taxes for a working public healthcare easily pays back in long term. The improvements can be seen anywhere if you just crawl out of your suburb nest for a while, better environment, healthier and happier people, who are now also able to work.
I think that's one of the sufficient standards for a democractic society; nobody is denied the ability to work in normal circumstances. That is if they are not permanently damaged so that they can't. The willingness to work is another thing, it can't be forced and the only option is just to put that much trust in your fellow citizens.
tl;dr
Forget what you've been told about who wants what and who benefits from what, think for yourself for once. Think about who really benefits from a better public healthcare. Hint: it starts with the first letter of your name.
