<p>“academic areas in business and economics don’t seem to be all that attractive to American kids, either”</p>
<p>– True. That’s because it’s more lucrative to get an MBA and work in a corporate setting at a highly inflated executive salary than to research/teach a purely theoretical field which will likely leave you a mere academic. The result is… subjects like advanced statistics being taught by, you guessed it, foreign TAs :)</p>
