I agree that honest capitalism is altruistic
I develop a better product; I sell it. I make money and you get a valuable product. Gates and company invent a usable computer and makes millions because millions benefit.
Marketing is not honest; people are selling an “opportunity” that can go out of business/change its comp plan/cost more than you earn etc. by pressuring, lying, etc. Gates does not have to scream at you for being a dreamstealing loser or show off his wealth in order to get you to buy anything.
