They tried this in Soviet Union with a state centered economy that focused on the workers, it failed. They tried it in China and quickly realized that the only way to grow their economy and make lives better for hundred of millions of Chinese, was a capatalist system. (This is by the way their still around, while the Soviets aren't.) And now Europe is having to deal with the problem as they can no longer sustain such lavish redistribution policies. The only way for socialism to work, is to have it setup in an isolated community, where better people freely only take what they need and give to others. As long as humans are the greedy, selfish people they are, and governments are as bloated and inept as they are, socialism will never work.
