As an analyst, you'll be making over six figures, with a base in the $70-$80k range. You can live 20 minutes from midtown Manhattan on that, though you'll probably have to have roommates (but hey you're 22 so again, no big deal).
N.B.: This was awful and I am now safely far, far away from the banking industry.
I do not think I could be coerced to work 100 hours a week regularly for less than $50/hour of cash and equity, and the lower bound might be closer to $100/hour.
If you've got decent odds of hitting the big payoff, that's one thing, but if the expected value is low, it just becomes another lottery, with a few winners, a lot of losers, and a the winners enriching themselves at the expense of the losers.
If you can put up with the hours until you end up as a director or higher, you can pretty reliably makes over a million dollars per year (with continuous increases in salary) putting only 50-60 hrs a week.
People do banking because it's one of the lowest risk ways to becoming rich.
