My daughter did preschool at the local YMCA. The program was excellent, as were the teachers. The administration was awful. Once we learned how poorly the teachers were being compensated, my wife and her friend organized a parent revolt. After about a month the administration gave them a raise of a couple of something like 20%. They could have given them more.
That said, the preschool director and our favorite teacher moved on once opportunities arose. We should straight up double the pay for all educators in the US as a start. It is very important and taxing work, and the consequence of quality couldn't be higher.
