You honestly equate a banker with a movie star or sports star? The average banker in the US makes less than $70k a year. Banking isn't a very good industry anymore.
That's not necessarily true, but scratch the banker example if you like, it makes no difference to the issue I was referring to.

Base Salary – Your most reliable income stream. You earn this regardless of whether you’re a superstar or a complete failure – at least until you get fired. Base salaries are $85K, $90K, and $95K USD for 1st, 2nd, and 3rd Year Analysts at mid-sized and large banks. Some elite boutique banks may pay slightly more, while regional boutiques may pay slightly less. Base salaries for Associates go from ~$140K to ~$180K as they move up.
End-of-Year Bonus – This is a percentage of your base salary, and it’s based on your ranking “bucket,” overall deal flow, and how much other banks are planning to pay. Some banks pay this bonus to Analysts at the calendar-year end and offer a “stub bonus” after the first 5-6 months, while others pay this bonus in the summer after an entire year of work has ended. Full-year bonuses for Analysts tend to be between 70% and 100% of base salaries, with numbers at or above 100% for the top performers. Expect higher numbers at elite boutiques and lower numbers at regional boutiques. Top Associate bonuses are 100%+ of base salaries.
