Hiwaytohell, I hope you're joking.
I don't know who you know in law and medicine, but EVERY single person I know that is about to start or is in their first year as a grad nurse, Intern, or paralegal is getting paid. I can assure you it is a bloody lot more than I ever got paid in my first 10 years of aviation. If you think I'm wrong look it up - and they don't have to continually hand out money for endorsements et al either.
This is just one example of grad nurses.

I don't care if it is a sport jumping club or a business. $5 per jumper per load and you've got a (probably) happily paid pilot. Finally, I'm sure you don't work for free, don't expect someone else to.
