Smart people will always gravitate to something like this to justify all the abuse. It was inevitable, reading this, I figured it was coming up in the first sentence.
Bankers are perpetually late on shit. The industry can barely manage to transfer money expediently. Listen to yourself. The abuse - which by the way is totally orthogonal to whether or not you work through the evening - is absolutely not about the workflow or timing or whatever, because I can’t think of a white collar professional more dogshit at doing things on schedule than an investment banker.
I’m confident 40 years ago the abuse was worse. And the money was worse too! They’re just not correlated. That’s the misconception, there’s no brilliant insight into how the abuse translates into more dollars. The real transformation in the industry is that the computers are better at making the real money than the human beings are, and like in many white collar professions, there are givers and takers of all that computer-generated surplus. Fortunately, when you work for a money printer, like at a giant tech company, some of whom have trading desks with AUM bigger than many hedge funds, you can relax a little.
