But exactly that SSTR will eventually stir up a problem, as the experienced older league retires: there will always be the pool of guys who have earned or inherited enough money to sponsor their TR, however it is becoming more and more expensive even to afford an ATP and the industry will be forced to invest in people again - it is just a question of time.
Although common practice with the airlines, I see some GA Bizjet companies are also heading towards funny psychometric testing to find the right candidates these days to minimize the risk of hiring the wrong type of people. If this really produces better pilots is of course questionable. I would however rather still take the chance of going through that selection process and get a ticket for good training and a subsequent TR, than spending all the money out of my own pocket in order to fly with some dubious company with people flying, who don't even belong there, for many possible reasons.
