The problem with the 'flight instruction to 1500 hours" idea is that is pryamidical. Suppose graduate 'A" has 200 hours, and needs 1300 more. He/she has to train 6.5 new pilots to make his hours, those 6.5 new pilots need 42.25 more, and on it goes. Its a ponzi concept. It won't work without a thriving GA industry where sub-1500 hour pilots can do air taxi work etc. as an alternative to flight instruction. That doesn't exist any more.
