"Flying instruction, 6 grand outlay to get a job that will pay u what, 10 k a year?"...
Possibly true, but it also gets you:
- Currency
- Contacts
- Great experience of flying in all sorts of conditions
- Great experience of working with the public
- Hours in the logbook
- Potentially some great friends
- Some great fun flying
- Valuable experience that some employers seem to like
Why not get all the above by doing some instructing part-time, having another job that pays the bills.
(By the way, if you're being charged 6 grand for an FI rating, you're being ripped off.)
