Capitalists earn money through control of capital. They're actually parasites that extract all the labour and value from others below them in the system. Capital is taxed lower than labour in most developed countries, at every turn capital is advantaged at the expense of living beings. There is no positive morality in this system of mass impoverishment.

I think we should put this to the test. The working class stops working for a week/month and we'll see how "productive" the rich capitalists really are.
