The nonprofit group Fight Crime Invest In Kids has released a study showing that it costs more, on average, to send your child to a private preschool ($4022/year) than it does to attend a Cal State University ($3164/year, and that's after the tuition hike). Well, obviously the solution is to send your preschoolers to Cal State, then.
In the Bay Area counties, preschool in Marin averages $4859 a year, in Santa Clara at $4700, San Mateo at $4697, and SF at $4572. This is all part of the buildup to the big state-wide debate about whether or not we should back Rob "Meathead" Reiner's proposition (no. 82) that we tax the rich for a free year of preschool for all California 4-year-olds.
