I agree with most of your points just that I'd tweak it slightly and say that Bill Gates vs the Hobo are better at producing, rather than saying that Bill Gates is better at creating demand. It's a very slight shift but it's important to recognise that it is the very act of producing that enables trade and the wealth that comes. Gates and the Hobo have the same ability to spend (ie demand) with the money you give them, but Bill Gates and the Hobo do not have the same ability to produce. That is why Gates is Gates and the Hobo is the Hobo. It is the fact that Gates has a propensity and skill to take the $100 and create value (production) from it that gives Gates the ability to grow the pie for everyone.
