All the way.
Also, do you see a pretty direct correlation between how far you went in school and your salary?
I haven't, but my going to school was more than just salary (although that was a consideration). I certainly should not have borrowed the amount of money that I did to get the advanced degree that I got. However, best evidence at the time was + $1,000,000 in salary over not having the degree - so I at least "thought" I was making a good decision.
I still hold just under $150k in debt and the only way that's getting paid off is through a government-backed program.
I would not have the good job I have now, nor would I be in consideration for my "dream" job for which I'm currently applying, so, on balance, I can live with the decisions I made - just bad timing.
