Convince me Capitalism is better than Communism

Before I am hastily called a bigoted Communist please let me explain. Capitalism is the system in which industry and trade are controlled by  private owners for profit. And the monopolies are basically the ones who profit instead of small business and organizations. So basically you work hard for nothing while the big guys barely work but because they are big owners they profit. Now in contrast Communism is the ideology  that practices values of goods and resources being available to all whenever they need it and being moneyless. And instead of the big guys slacking and getting paid for nothing here in communism everyone is paid according to the abilities and needs of the individual. So you may challenge and say that communism will cause anarchy, and this could happen due to it being classless but still if this would be able to happen some values might be changed and a "leader" so to speak would have minor control.
