Re: competition. When I mean work their way out, I mean retirement. Ineffective teachers will retire, and with higher pay, the increased number of applicants for teaching positions will raise the bar for new teachers. In the article, it said like 6000 applicants applied for 600 spots. That's the kind of ratios we need in the US.
