"Companies don't get rich hurting their customers."

Previous Quote

I mean people -- people don't get -- they don't get smarter about things that get as basic as greed and you can't stand to see your neighbor getting rich. You know you're smarter than he is, and he's doing these things, you know, and he's getting rich, and your spouse is getting unhappy with you because you aren't doing -- pretty soon you start doing it. And so you get what I call the natural progression, the three Is. The innovators, the imitators, and the idiots.
