Just to be clear, I didn't mean to imply that it was okay. My text does read that way and I appreciate the opportunity to elaborate.
I too would like the world more if there were less of that. I can't think of a lot of philanthropists off the top of my head who made their fortunes from unambiguously morally-good methods. My personal opinion is that we're probably on an upward trajectory. Comparing how Gates made his fortune with the Rockefellers, Vanderbilts, Carnegies, etc. I think Microsoft comes out on balance a bit better.
