How can you make it with economics

Kind of obvious but what do you think?

Easy.

Get a PhD, memorize the top 50 words that most people have never heard, and teach college until you can BullS**t your way to a top government adviser position.

Without a PhD, teach high school or get a job for a huge financial institution.

Added to any of the above, write a crowd-pleasing book with some novel theories in it, like Freakonomics. Loved it.

Good choice! You don't even have to be right to get paid.
