I mean do you understand that investors make decisions based on rational calculations of expected value? You can absolutely reduce individual decisions to numbers (or "economics theory" if you prefer)
I thought the problem was that Will was being thoughtless in using the economics jargon meaning of “irrational” and people were misunderstanding.
I was being too generous, motherfucker actually thinks “economics theory says the optimal choice is…” defines what is and is not rational for individuals
