Capitalism allows people with money to make more money easily, while communism allows people with the power to make more money. The social structure in capitalism, communism / socialism and dictatorship is different, but all classes still exist!
Whatever sort of structure it is, you would be succeeded only when you try hard to live your life. In reality, it is bitter truth that in both communism and capitalism you are going to get nothing. In end, there would be some other group of politicians who are using you and they are pinching off every single moment of hard work from you and utilize it for their own profits. This is what happening.
