As I said, in SMALL ISOLATED COMMUNES... COMMUNism works, it's the only way it has ever worked, and I'm sure they have greater EVERYTHING than the US, because small, tight-knit groups can utilize socialism to their advantage. We can't do that here because we are a nation of 350 million people, of all walks of life, no one knows or trusts each other, we are consumer driven and mobile, on the go. We have millions of illegal immigrants flooding our emergency rooms and schools, that a socialist system simply can't afford...HELL, a Capitalist system can't even afford it!
You seem to be fixed on the idea that size matters Mr Boss, so why don't we go straight to the big enchilada? China is a country that has amazed many over the past few years, by going from a poor backwater to the number 2 economy in the world within a couple of generations. This has been done through state controlled capitalism, ie: bureaucrats making all major economic and financial policy. This is Scandinavia on steroids, not a high tax, high service economy, but a controlled economy. It is a form of government control that would have had even FDR looking at the ground and scuffling his shoes. Yet they have taken off. All 1.4 Billion. And yes, they still have terrible problems with poverty and environmental destruction. But so did Britain when industrializing in the 19th century, as did the US also in the early 20th.
You are making the stereotypical mistake of assuming social programs are unafordable, a luxury to be instigated only after the "real" economy is taken care of. In fact, they are an artifact of philosophy, not of economics. Communist or capitalist, there is only so much produced in a given time frame, and people will still need and want certain things. In some cases, private direction seems to make sense. In others, public ownership makes better sense. These principles apply in either large or small juristictions.
I also suspect you are a rather young man, as you seem to accept the current over the top consumerism, and general self-interest and paranoia as the norm in the US, although it is not. The US was much more cohesive, going back a few decades, and the political sentiment was also further to the left than it is today, in most regions anyway. Consumerism and individualism bordering on anarchy are concepts that have been whipped up by the uber affluent in your society, for the reason that it benefits them. It benefits them to have a low tax, low service, unregulated, greedy, free for all society, as that is how they make their money (and keep it). When you make $30M a year, you don't need medicare. So why pay for it? Screw everybody else. That is the current belief system for those at the top (well, most of them anyway). That's why there is a relentless blast of spin from those so mentioned, and it has influenced the credulous and easily swayed over the last couple of decades- such as yourself, apparently.
