"should I Go To Graduate School?"

Should I go to graduate school?
Short answer: no.

Over the past five years, the number of graduate students entering history PhD programs has been rising, while the proportion of faculty approaching retirement has been falling. And looking forward, the U.S. Department of Education anticipates that the recent growth in the number of new undergraduate students at American colleges and universities will slow down over the coming decade--about the time it would typically take someone just starting a history PhD to finish.

There's no shame in dropping out, either. Smarter people than you are flourishing in nonacademic careers, and I invite you to bite their asses if you think your "Dr" means anything.
