It's a difficult issue. Ultimately pilots can only be paid out of profits, as no profits = no company after a while. So it stands to reason that to get a decent wage you either need lots of revenue pax or just one who is willing to pay a lot per hour.
Students who go shopping for the lowest hourly rate help to drive down wages - but who can blame them?
Become an instructor anyway if that's what you want Yorkshire-lad, and when you get some seniority you can lobby for wage increases - not your own wage, the juniors'.
It's a hard world out there no?
best of luck anyhow. O8
PS - my pet peeves: instructors who work for nothing, and instructors who are paid a salary and work overtime without claiming for it. Both the same thing really.
