I remember reading about dark pools and asking a friend in finance if the sector really is as corrupt as it sounds, his reply? "Oh much more"
The only reaction more adverse than the one you get asking coders about remote voting is the one you get asking finance people about transparency and anticorruption. It's an open secret at this point that any effort that would weed out a significant proportion of the fraud would cripple our finance sector overall just because everyone who runs it would be in prison.
i don't know who you're talking to but no, it's not that criminal. it may be "corrupt" in the sense of rent-seeking or recapture-heavy institutions. it may be "corrupt" in the sense that your average IB analyst knows he's pulling long hours to churn out reams of 80% BS. it may be "corrupt" in that the VP at a PE fund knows that 7 turns of leverage and an inflated multiple for this middle-market shitco isn't actually a good buy. but there are a lot of honest people, enough that you can choose to do business with the same.
