So what?
The flying schools are businesses that need to survive. They only do that by selling their products. Those that they employ can only pay their mortgages/rent and other bills if their employer has the income to pay them.
If this chap or his parents are able to raise the funds to pay for this course, then that is their business. If they want to go out and buy a Mercedes SL for the same sum of money, that is equally their business.
Whether this chap or his parents are relying on this course to provide a short term return is something that is incumbent on them to research and decide. The poster isn't asking for an assessment of the market place or more "expert" opinion, he simply wants to know if anyone else is expecting to start on the course he is proposing to join.
