lol!
I wonder why the turnaround is so horrible in the first five years if it is so easy.
True. I've known a few businessmen who went into teaching in the city because they wanted to do their part for the schools and the kids. They got chewed up and spit out. But yes, some do succeed.
The least liveable aspects of the job are the stupidity of the theory one is expected to parrot and political crap from the bureaucrats. Both of which are utterly unnecessary. You could fire a quarter of those in the education business (above the classroom level especially) and quality would improve.
If anybody thinks it is hard, then let anyone with a bachelor's degree start a school for vouchers anyway they like. If all that centralized crap actually helps, they will fail. But they won't fail, and absolutely everyone involved knows it. (See charters). That is why the left won't even allow the attempt.
