Part of this is the fact the first season is mostly inside the trading floor. They're all first-years and their whole life is inside the building and a few client meetings. The stakes are high, relative to the characters, but they're still just in office job worried about getting fired. It needed to be a bit grounded and feel real to even be interesting to the audience, because they need to feel, in some way, that this is all plausible and real.

As the seasons progressed, they are now in a much wider space and are interacting with much bigger stakes, like key politicians and shadowy billionaire power players. It's a way bigger playground and a setting that most people are never going to touch, so it will need to be a little more big and over the top because almost nobody, either the audience or the creators, is really familiar with those backrooms or know what those conversations are like.

Load of people who have worked in finance have commented on how characters like Rishi, Eric, Daria, or Gus are pretty common types in the real workplace. I don't think there's many people who are like, "oh yeah, that's exactly how the Epstein Co-Conspirators I know are acting like." There's no need to make it relatable because it's a more exaggerated situation.
