It isnt. Its the parents responsibility. Someone sold them an idea and then unioniized the teachers. Henry Ford built his own school. Andrew Carnagie helped create the public library system through his donations. Most of the elite in Washington use private schools along with the very rich and some teachers. That probably increased after the state mandated that rich neighborhoods, say like Mercer Island were given the same funding as neighborhoods like Renton, but did nothing about the disparity in property taxes. So much for shoping for the best school.

Does it ever make you wonder how the entities most involved with government are the most screwed up?
Education and health care.
