I used to work at a small flight school. The owner was from the Netherlands and he was sometimes harshly reminded of what is important in America. It was astounding how expensive it was for him to keep operating even as he did his own aircraft maintenance and repairs when legal, he was also AP certified in addition to CFI certifications. He did everything he could to help students control the costs of their education. Then as students proceeded towards a commercial pilot job usually via attaining CFI certification to build hours the owner would try to recruit them as instructors. When he hired instructors they seemed to be two specific types. Retired pilots with 20 plus years of bad habits to undo, flying a computer, or newly minted CFIs with zero skills. Both had to be reeducated as to get them up to speed on the owners instruction methods. The newly minted CFIs were far more common usually taking two years to build hours and they were gone to the airlines and the owner had to start all over. I have always thought the airlines should partially subsidize the flight schools since they were the largest benefactors of the program. Another thing that stood out was the monopoly Garmin has on glass panels. The cost of upgrading training aircraft with electronic instrument panels sometimes exceeded the value of the aircraft which could never be recouped through sale of the aircraft. If you compare this to the number of cost effective instrument panels in the experimental aircraft sector the comparison is obvious. Of course the experimental aircraft panels are not FAA certified.
