>>3 Sadly, logic and reality are separate entities.
The "Utopian" idea that is communism sadly cannot exist or at best has a minimal chance of survival in reality. This is because of human nature. Those with power wish to keep it and those without try to take it (working and middle class). Those with luxuries tend to work at perserving their way of life (upper-class). And no matter what they have the masses always want more.
Communism tends to work by suppression.
Individuals think for themselves and the masses follow by example.
So if you can suppress/remove the leaders of the masses the masses will follow the status quo.
The government controls all of the money, the land, the peoples’ possessions, jobs, power... and in some cases like North Korea, dictate your life as well as punish/remove anyone you personally know if you attempt to escape the country or the life they provide you with.
And also, I am a citizen of America; if I may I would like clarify about America.
1. Your numbers are actually kind of close; the richest 20 percent has about 85 percent of the wealth. The next richest 20 percent has about 10 percent of the wealth. And the remaining three-fifths of America share a tiny sliver of the country's wealth.
2. We have jobs, I see quite a few everyday (and I mean available jobs) but people think they are too good to take them (and some of these are actually pay very well). If the remaining 60% took these jobs the numbers would shift accordingly.
3. And even with the money distributed the way it is, even the poorer people have a higher standard of living than a lot of countries, and yes I understand some of the poorer masses are having a hard time in the economy with the crash of the DOW.
4. Our welfare system is messed up in favor of the people, there are people going a good 3-5 years on it without trying to get/getting a job.
Capitalism does work, it’s not the best system but it is the currently the best system that is compatible with reality. And America's problems come from the people and not the economic system or the government. And besides, this is what the people want as to retain their freedoms... but that’s a different topic to diverge to.
