Communism does not fail humans might fail in the attempt to achieve true Communism but if done right, it will lead to the equality of all humans, not just the rich, or the current system we have of getting rich or die trying. I'm not myself a Communist since I really don't see as humans, especially us of the West who are so use to live in a materialistic society, but I do believe in Democratic Socialism, it works pretty well in Northern Europe, why not imitate nations that are doing way better than us ?
Where in Europe ? You do know that there are quite a lot of countries in Europe right ? And if you had read my comment correctly I specifically said Northern Europe and they are not doing bad at all. Watch some Noam Chomsky, enlighten yourself.
