Why did John D Rockefeller not care about people he destroyed to become a multi-billion dollar monopoly?

Why not acknowledge that he also gave jobs to quite a few people who worked for him as he made that monopoly, and they paid for the things that THEY wanted. It's a classic position of the people who want to blame the rich for all of the world's problems. The reality is, the rich got that way by providing goods and services that the rest of us want. If you don't want to contribute to the Bill Gates empire, don't buy any Microsoft products. But since Gates has provided something that helps the rest of us be more productive, you need to acknowledge that he isn't just a "robber barron".

Same thing with Rockefeller: he provided as much as he took.
