First of all, what would one define 'lower class' as?
I started training for my PPL at 14, and got it at 17. It was paid for through inheritance from my grandmother, a year stacking shelves and saving at Sainsburys (something I still do now to pay for flying and having a bit of fun at the weekend) and a fair amount from my parents. All this on top of school/college, its been a busy few years, but I can gladly say I've earnt my PPL.
I have absolutely no plans to put my parents in financial risk to fund my commercial training. They will be paying for some of it ,but so will I. I'll be flying modular, something I always planned to do, and will be able to work and fly at the same time (most likely not at sainsburys mind you, I'm at the end of my tether)
Financially, short term, it would be alot easier for me to take a loan out, and go integrated in september next year straight out of college. But I hope this way I'll be free of significant debt, and still enjoy myself in the process!!
Cheers!
