Historically, Liberalism was a reaction against the very kind of poverty you are talking about; poverty caused by too much Government intrusion into the Economy.
How did these people profit off the labour of others? They were intellectuals; professors like many Socialists. What about the fact that most famous European Socialists are also from Rich, Elite families? What about the fact that Adam Smith, Friedrich Hayek, and many other Liberals were great philanthropists, donating much of their income to various charities?
Frankly, I think you hate Capitalism too much to be objective about it.
