A tiny number of everything makes insanely lots of money: Developers, Lawyers, Chefs, Engineers, etc. Speaking for that tiny number, does Google, Facebook, Microsoft and Apple's top management (who are or were developers at some point) qualify as developers? If yes, then there's no comparison I guess.

That said is more than obvious that in a digital world the future belongs to developers, because the demand for them will go up, it's inevitable.
