I'm willing to bet that the average professor of physics is 10 or 20 IQ points above the average medical doctor.
Too bad IQ doesn't mean anything, huh? Or else you might have actually had something there.
You can't compare doctors to scientists. If a scientist doesn't keep up with the world around him, he can't do anything (related to his field) and drops out of the race. A doctor can just open up a clinic.
I went to a doctor once with a bad knee. He told me not to squat down or do anything that involves bending it for about 10 years (my injury wasn't very bad and you see athletes back in the game not even a year later. That's because they REHAB it, not just sit around). Wow, that was really worth my $300. Next, I went to a dentist that fudged 3 or 4 of my teeth and now I need root canals. Awesome.
But, the GOOD doctors do keep up with everything. It's just that there is no real incentive to be a good doctor.
What do you call someone who graduates at the top of their class in medical school? A doctor. What do you call someone who graduates at the bottom of their class in medical school? A doctor. What do you call someone who graduates at the top of their class in um... physics school...? A physicist. What do you call someone who graduates at the bottom of their class in physics school? Unemployed.
That being said, doctors aren't exactly stupid. They get payed more, sure, but they aren't brain dead. They still had to take a lot of hard classes to get to where they are.
It's all about supply and demand. People get sick all the time, so they go to the doctor. Physics on the other hand, just keeps getting harder and harder and there hasn't been a breakthrough in a while.
Science has never been about the money. Rich people way back when didn't do science because they wanted to have more money, but because they liked it. Galileo didn't piss of the church because he wanted more money, but because he knew science was right.
I understand that it seems like a bleak future, to spend so much time and effort and have little to show for it. But it's not about doing to get something, but doing for the sake of doing.
