Would you rather

A recent conversation with a friend sparked this question.

You have to choose a career. You love both careers equally, benefits, hours, etc. All money is at standard interest rates and wages increase at the rate of inflation. Its strictly down to the money and when you get the money. Would you rather have...

Career A where you earn 100k/year starting at 20 years old with no debt.

Career B where you take a path of an MD. College debt, delayed earnings, residency, the whole shebang. Your average annual Salary is 325k for your career.

At what Career B average salary do you think these careers are roughly equivalent on net?
