It was not my intention to pick on the hours builder. Most of them try to do a good job and a lot of them like instructing. Every pilot wants to move up to something bigger. To do that you have to build hours. Doing it as an instructor is not bad. Flying sightseeing tours probably gives you way less experience in the same number of hours.
For a pilot in the US it is often the only possibility to build hours. For a 135 operation you need a minimum of 500 hours. There aren't a lot of 91 jobs around. The insurances make it even more difficult to find a job.
It is not important how many hours the new instructor had or who much time the instructor course took. It is what he learned and what attitude he has towards flying and towards his students. And there are those things, that you can't learn in hundred years which make the difference between an good and an excellent instructor.
