Just did a search on "preschool teachers." Google nicely presented this info on the RHS of the screen. While all the research & intervention points out how critical our early childhood years, the ones who are responsible for developing them are paid right around minimum wage. And we wonder why US education system sucks. Why would you go into this profession at these numbers. Even if these numbers are off by 2X or 3X, they still cannot afford to live in Bay Area.
