Yeah right! That made me chuckle too, being a flight school owner, I am hardly rolling in cash, and nor are any of my competitors. Most of us are spending most of our turnover on keeping our elderly aeroplanes airworthy, fuelled and insured. "Hefty Profits" bwahahaha and the old chestnut, if you want to make a small fortune in aviation, start with a large fortune.
Where there are wealthy flying school operators, you can bet your boots that they derive their income elsewhere and are probably using the flying school for a tax loss. Some flying clubs are wealthy, but usually it is the bar and membership fees that keep them this way, not the flying.
As for the chap quoted above who thinks that he has a right to cheap flying because he is a student, well maybe he thinks he is entitled to a brand new mercedes and an free house too. He obviously isn't doing an A level in economics.
If he came into my flying school I'd love to hear him explain his thinking to the "middle aged businessman" who has probably been slaving away for many years to be able to afford to fly and have all the "normal" things like family, house, car etc and try not to have a heart attack in the process.
Let's hope this thread stays among us pros and those others aren't silly enough to butt in. Otherwise I might have trouble resisting using my moderators muscles!
