The philosophy of the NHS and equivalent schemes is that everyone pays in 1% (or whatever) of their paycheck, every year.
All the time you're being healthy, that 1% is funding people who can't afford to pay for their operation/treatment (which can run to tens of thousands of pounds). You may consider this unfair.
On the other hand, when you are made redundant and can't get another job, or when you're a single mother whose scumbag partner has left with a mortgage and two kids, or when you're trying to make your £6000 pension stretch an entire year, you don't need to pay for your healthcare. What goes around, comes around.
And if you never need to use the NHS for anything at all what are you complaining about?
That seems to be the kind of attitude Obama is trying to instil in your "system". I don't really understand how apparantly millions of people can be vehemently opposed to it... but that's probably dragging us way off topic already.
As nice as the NHS is think of the size of Britain and the size of the U.S.
People in the UK complain that the NHS is a sink hole when it comes to funding and spending of the national budget,
Is it good? Yes
Are there flaws? Of course.
Now take that system and try running it across a continent (which the US essentially is due to its sheer size and population, btw, I'm not ignorant I do know America isn't a 'continent' but in terms of sheer size, it China and Russia are close in a way).
Who would run it, the Federal Government? They can barely manage things as it is.
Healthcare, like most issues is a State issue. why should healthy people in California pay for the morbidly obese Texans? Let them pay for themselves.
Plus I don't like the idea of paying for someones abortion when they use it as a method of contraception (excluding rape/life of mother), or someone who eats McD's all day and can't leave the house, or someone who smokes themselve into an early grave, or does drugs etc.
In the UK every weekend the NHS is filled with idiot drunks who cause nothing but problems, why the fuck do they get treated for free when their own idiot actions resulted in their situation? Then the fuckers go and do it all again, and sometimes even attack staff who try to help them! Sure its a minority, but it still happens and isn't fair or right.
Anyway, if it was a State run, State taxed NHS system, with each State deciding whether or not to implememnt it I'd be all for it.
But in America you would more than likely have to allow people to opt out of it, or you will get a whole Supreme Court session, protests, un-constitutional blah, blah session.
