As long as educated and wealthy people who don’t want to hand over their wealth exist communism will fail. If you “get rid” of these people your society is left weaker due to brain drain and those who remain are left worse off. Imagine being super intelligent and generating vast wealth with your labour and intellect then being forced to hand it all over and watching it get wasted by the government on projects you know will fail and given to lazy unintelligent people who enjoy all the benefits of your work while you get nothing more than them in return for your extra contribution
