Well that's two IR's that suck all your money dry then!
While I agree that FI's should be paid more, considering the expensive training, usually at their own cost, it is simply a case of supply and demand. There are more FI's than FI jobs, most FI's are willing to work for low money on the basis that they are building hours for an airline job and while that continues, most flying schools will probably go for the cheapest FI's they can.
If FI's wages go up, PPL prices go up, less people will take up flying and they'll be less instructor jobs. Most PPL flying schools make very little margin and they would have no choice but to up their prices.
Basically FI's need some sort of external monetary input from the government. They give money to struggling musicians under the new deal, yet this industry probably provides less revenue per person compared to flying. Meanwhile, pilots get absolutely zilch.
And do you know what I've just found out - Avgas is heavily taxed wheras JET A1 isn't. So people trying to train for a new profession are taxed but people who are going on holiday are not. Doesn't seem fair to me.
Anyway time for bed.
