My fear is that GA will follow sailing (esp. yachting).
If you mean by cost, then yep! Cost me and my brother £3500 to keep our yacht in a Marina (no alternative), and thats before any extra c**p like winter storage, anti foul, maintenance....Call it £5000 per year. Hmm, almost the cost of operating a PA28...So I sold my half eventually
Only someone with no business sense would run up £60k in debt to become an instructor. I think the £60k debt person has the ulterior motive of becoming an airline pilot, being paid a decent salary.
There is no need, if you want to become a career instructor, get a job, pay for your flying in chunks, and then enter the world of instructing 3 years later with no debt.
Unless of course you are aiming for a RHS of a Boeing.....
