Very little value added at all but much extracted.
Bloomberg terminal subscriptions with $20k+/year licenses as one small example. The equivalent of an Oracle to many on here and the licensing most despise but for some reason nobody questions this guy? Or Bloomberg/CNBC/similiar in general? Or anyone peddling any financial stuff? Would we just trust a big co enterprise salesperson that's been around the block? No we wouldn't.
Anyway, he said of Archegos before:
"But one thing I want to say about the banks is that if you were one of Hwang’s prime brokers and you had perfect information — about how big he was and how concentrated, about how many banks were financing him, about his effect on stock prices, about Viacom’s stock offering, etc. — you might still rationally do this trade, if you were confident you could get out first."
You'd have to be part of the system to make a statement like that.
Banks take deposits and list them as assets. And then get risky with that money they have relatively low cash reserves for. And when they screw up, it costs them less than what they gained. It's ridiculous.
The financial engineers' version of rational is reckless.
