There can't be enough rich people to support a significant move upmarket of the entire training industry
Probably not to fill every flying school at every airfield with eager customers able to spend £200k on a plane, or £50k on a share, the moment they get their PPL.
But anyone doubting how much money there is needs only to stand next to the M25 and count the £40k+ cars driven by under-40 year olds. Just 1% of that money would transform GA.
The money is there OK, the punters just choose to spend it elsewhere.
Some people think that attracting better-off people to GA would make it more expensive. That's wrong, because operating a new plane doesn't cost any more than operating an old one. The old one costs less in financing but one spends the "saved" money on a constant stream of "little suprises" and the occassional big one.
Presently, GA receives a massive subsidy from all those students who spend £5k-£10k on a PPL and then give up. For the schools this is just as well, because - short of having a large self fly hire operation - they wouldn't be able to capture the customer's ongoing spending. I am sure they know this, which is why most don't exactly encourage PPLs to hang around when they have done their PPL and possibly the NQ.
