OK, OK I agree with you.
It would be nice and lots of piloting skills would be learned if cubs etc were used. They are just not available like they were. By the way a C-150 is much more civilized than even my PA-20 Pacer and the cub. The Aeronoca was (is) a nicer flying plane than the cub and faster too. If an airplane is too easy to fly the finer points of piloting can be lost. If the instructor doen not make special effort to point out those points that are masked by the detailed design of the craft.
The C-150(2) is civilized enough and picky enough to be a good trainer as long as the student and instructor are not too heavy. The C-172 is good too, but cost more to operate. It also is easier to fly as most larger airplanes are.
I had a couple of Ex Russian instructor pilots at my school who wanted US pilot's licenses, We had to start in King air 200's and work our way down through lances, C-182, C-172 to the C-150. They thought the 150's flew like butterflies.
They eventually got the hang of it and one of them now flies for FedEX. (big iron is still easier to fly and pays better too!).
Neither the Cessna nor the Piper are particularly better or worse aircraft, but the design philosophy is different. In my opinion Piper never made a trainer after the Cub series. They chose to compete at the Cherokee-172 level. For transportation they are roughly equal year for year, which is what competition is all about.
If you really want to learn how to fly airplanes-----I got this PA-20/150. Now then that airplane will teach lots about the art and science of flying for those wiling to learn.
