But profit _is_ the driving force of human action. Doing anything voluntarily is by definition profitable, otherwise you wouldn't do it.
I can pretty much guarantee hunter-gatherers hunt to not starve, children play for sheer joy, and nobody's thinking of profit.
There are better psychological/anthropological terms to apply to human drives than calling them "profitable". That's weird economist thinking, trying to bring everything under their purview.
At least that’s what is going on when the schools of “thought” this kind of stuff comes from attempt it. This particular poster might not be. But usually it’s a cheap rhetorical trick, coming from folks who present themselves as simply following logic. Gross.
