A combination of pension obligations, declining enrollment and rules that require the education system to address social inequalities have put California schools in a vice. Even though they get more money, there’s less to spend on students and today’s teachers. Zocalo Public Square columnist Joe Mathews says the squeeze means a smaller percentage of California adults achieve college degrees and fewer are graduating from high school. Solving the problem will be a huge challenge, but Mathews says we should start by scrapping current school funding formulas.
