Zero. It has zero to do with how California treats its most vulnerable immigrant population, and everything to do with how California funds its schools.
The Berkeley CA School board recently had to make hard choices in its yearly budget. Berkeley is one of the wealthiest cities in the state. It was forced to slash safety officers and special programs due to a $2 million dollar budget shortfall. Less than the cost of a house. [1] America funds its schools primarily via property taxes, so Proposition 13, a measure that freezes that tax revenue, keeps $2 million dollar properties taxed as though they were valued at ~$100,000. It ensures California schools will always be begging to meet the needs of the state's growing population. [2]
