I am writing from the Czech Republic, which is even more socialistic than Sweden. For example, the current government is extremely unpopular because they introduced 30 CZK (~ 1,1 EUR) fee when you visit a doctor. Our public debt is 27 % GDP, which IMHO bad, although still much better than Swededen's 42 % (so much for the "living within our means"). But I can only laugh when people promote (semi-)socialism over the free market. I also laugh when they pride themselves on their country statistics.
Life expectancy, for instance, has very little to do with the health care system, once you live in reasonably civilized country. We have very socialistic healthcare system, nobody has to pay for anything (not counting the recent desperate 30 CZK attempts to bring at least some market in healthcare to stop people from squandering), we have skilled doctors and hi-quality medical apparatus - quite comparable to the western europe. However, we have the life expectancy only 73.3 (male), whereas Sweden has 78.5 and the US has 75.3. The main reason why we fall behind both US and Sweden is high consumption of alcohol and cigarettes (double the Swedish). The highest life expectancy can be found in Macau (81.3) - therefore we all should adopt their system?
I agree that capitalism is not everything and that semi-socialist society can prosper as well, however it requires some specific attributes on the society, like strong tradition, morale and man-nature, which suppress abusing trends. Such society is also more fragile when undergoing various internal changes and movements. BTW: How do you manage the immigrants in Sweden? I heard that you are facing some really challenging issues in the welfare system...

I am writing from Sweden where we are semi-socialistic. We have a much higher quality of life than you Americans. Actually most of the EU has a much higher quality of life than America on average. For example longer life, better rudimentary education, and the legal right to 4 week vacations every year. Why are Americans so afraid of socialism? Is it the poor health? We still live longer than you Americans. I digress.
There are plenty of free-market economies ( I think that is the term for the US economy?) as well as socialistic ones that have failed. It seems to me that it is not socialism or market freedom that correlate with economic success but the morals and values of the underlying culture and its leaders. Particularly I think political and economic restraint are severally lacking in America. The sole problem America and other debtor nations face is simply because people lived outside their means. It really is that simple. And that is something that is just as much a factor of cultural ideaologies as it is legal/ governmental ones.
My simple Swedish solution is to live within your means and help other people when you can.
