The problem I see with socialism/communism is that it goes against what I consider human nature. Ideally, we'd all produce for the good of society and only take the minimum of what we need, but human nature is not like that. Most people want more, want to better their life, want to marry the most beautiful mate, drive the fanciest car, take the best vacations, etc. While many of the European Democratic Socialist countries have very few really poor people, there is little to no incentive or way to move above lower- to middle-class. None of those countries, while possessing things the US could adopt and make us all better, would be considered the Land of Opportunity and, while certainly not perfect and perhaps to a lesser degree than previous generations, America still is that land. At least that's the way I see it.
