There is nothing wrong with a year or three in industry. You'll be a
much better coder, get exposed to problem domains outside the typical purview of twenty-something white and Asian males, build contacts, and improve your soft skills such as how to wear a suit and talk to people older than you outside of the teacher/student relationship. These things are enormously valuable.
If you're worried about getting spoiled by the huge paychecks, I recommend being a Japanese salaryman. We would never dream of inconveniencing you in that fashion. grins Seriously though, if you put $4k a month towards your student loans (or a savings account you solemnly promise not to touch) your $80k salary will feel like, what, $20k or so after the tax differential?
