The only professions that I can think of that have that possibility are: doctor, trader (finance) and investment banker (finance) and possibly lawyer. Anything I missed?
Cardiologist salaries have nearly doubled in the last decade to a hefty $442,000. That's not to say most doctors make anywhere near that, just if your in it for the money there are choices you can make to get there. However, 400+k is not exactly what it used to be which is why so many people are still focused on the financial sector.
But his point is still valid...tech people could easily have gone to med school. If they had...they would have had a more solid chance at accumulating that USD10Million than working startup after startup.
> tech people could easily have gone to med school.
Some, but mostly not. The non-tech professions that offer high pay (medicine, law, banking) all have very different barriers to entry than tech. There are a lot of folks who made a ton of money in tech who didn't have the 4.0 + ridiculous extracurriculars to get into med school, or the Ivy-league background to get into a bank. I think those barriers make those professions less meritocratic than tech, don't get me wrong, but they are what they are.
Let's not forget personality / human factors though - I'm fairly certain I could have been a doctor or lawyer (even considered being a lawyer at one time and got a 178 on the LSAT) but I'm just not cut out for those fields. I'm too squeamish to be a doctor and I don't have the interpersonal / political skills to be a really successful lawyer. So tech it is...
