The salary distribution in this business is highly skewed. Lately, salaries have increasingly included an equity component which may not be liquid for up to three years.
Some firms tend to pay less than others because they can get away with it.
You might actually be better off taking less. You are trying to maximize the present value of your future earnings and enjoyment. This may involve taking lower pay now. Salaries in money management are likely to be mainly a result of performance. Pay in real estate depends greatly on what you do.
