i dated a guy at MIT who was pretty close to my IQ. he had a
dual major in math & philosophy. my dad asked him at dinner
once what he planned to do with that dual major. BFs reply was
a thoughtful "Well, there's really only two things i *could*
do with a dual in math & philosophy. I can either teach, or
become a farmer..."

Today there are more options. Many math majors from MIT have the
aptitudes to make a lot of money on Wall Street as quants or (even
better) traders. I got a PhD in physics and took the former route.
Math skills are more valued on Wall Street than they were say 30 years
ago.
Some mathematicians have done very well managing money themselves, for
example James Simons:

Consulting companies are also looking for generally smart people.

A significant fraction of people from elite universities that I know
of are teaching at test preparation companies such as Kaplan. I think
such companies require high test scores from applicants.
