people make decisions, yes
but these people are selected by power structures to make decisions that favor the shareholder's return on investment over anything else
if these people privilege interests that conflict with shareholders', they get replaced
factor in that stock trading is currently controlled by algorithms, and that the humans in charge of them make decisions about them under similar constraints, and you should quickly realize why the dominant species in the planet is the corporation, an early form of artificial intelligence that we now serve, and that doesn't care at all about our future, even if it still depends on us to carry out its actions
that's the reason why we seem so doomed
we must take control back from them very soon if we're to stand a chance of surviving
