>>510087565 (OP)White-hot people live further away from the equator, which triggers two factors. Firstly, people closer to the equator have to take more breaks because of the heat - that is economically relevant.
But more important. The further away you are from the equator, the harsher the survival conditions are. That creates civilizational pressure. Where people live in abundance, things come to a standstill.
So yes, I think you can prove it empirically.
