Philanthropists,Self-Hating Capitalists

You hear it all the time.Philanthropists are doing it to 'give something back'.What?The implication is obvious,these people have taken something from society and by becoming philanthropist they are now giving something back and thus redeeming themselves.Bollocks,sorry.They have created value,introduced some innovation in production and the market and provided a service for which they have been renumerated.But they have been taxed on an industrial scale.And they have provided work for thousands if they are a very successful entrepreneur.They have 'given' far more to society than all of their critics put together.The only time they become parasitic is in their philanthropy when they seek approval from others for their misguided altruism.That is sad and it plays into the owing something and putting something back rhetoric/narrative of the liberal critics of capitalism.
