Then & now
Those old enough will remember when "brain drain" was an issue - 3rd World countries losing their best & brightest to the USA. No one at the time would have guessed that the "solution" would turn out to be the USA turning them away.
As others have posted, a generation of the domestic best & the brightest studied how to move money around instead of make things. Unemployment for law graduates is at a record high. I haven't seen the stats for finance degrees. It's only natural for people to choose health/medicine careers. It's a guaranteed growth industry given the aging population. And there's less chance of wondering if your work has contributed to killing people or wrecking the environment.
Finally, there's concern about why young women aren't choosing STEM education/ careers but I haven't seen anything yet about how that concern has led to changing those stats.
