Why can't you go to uni and have a part time job to save for your flying?
It'll work out for me (all going well ofcourse!). I live in good ol' Oz, so it'll cost me aboust $50K all up. That works out to be about a third of what you will have to pay though. Anyway uni is great. I earn just enough every week to fly and put some money away for my CPL. I'm doing my ATPL as an elective through uni, and I fly privately every month.
Uni isn't for everyone though. But it has helped me learn how to learn.... if you know what I mean, and the life is great (when I can afford to go out). Having said that, I don't think that I would enjoy a trade if I lose my medical/flying job, so uni is probably the best option for ME.
I also believe that to get an airline job in the US, you must have a degree and although that isn't the case here or in the UK now, it maybe in the future.
Anyway, my recomendation is go to uni, but make up your own mind.

PS if you decide to go to uni, do something that you enjoy. I started out doing IT and found it very boring.
