Communism's Theoretical Failures: Communism strives for the complete equality of all incomes, and therefore, everything. As income approaches complete equality, productivity disappears. For example: people work so they can make money to support themselves. They work driven by the incentive of making more money and succeeding. In capitalist systems, he who chooses not to work suffers the consequences while he who works receives the incentives, money, which he is working for. Human nature includes a desire to "do better" and, therefore, make more money or advance in a job. In an attempt to make more money, people are driven naturally work harder and longer, seek further education for themselves, and develop skills which distinguish them as rare talents among that labor which is available as supply. Under true communism, income is completely equal. When there is nothing to achieve by working harder or longer, people begin to become idle. People begin to work less or not work at all because there is no longer the incentive of making more money or advancing in job. When there are no workers, production drops to nothing. It will then be true that all incomes are equal but this equal income will be zero.
