I just saw the most bizarre comment on Facebook linking Prop 13 (property tax limits) to California's horrible schools.
Even a cursory Google search would disabuse the mildly literate of that silly notion.
Prop 13 doesn't seem to have impacted school spending at all. According to the California Department of Education, schools spent $8323 per pupil in 2010-11, up 55% from 1998-99 spending, which is growing much faster than the rate of inflation.
And that's far more than other developed countries spend.
And that's only operating costs, not including capital costs, which drive per-pupil spending to near $30,000 in some places! For that amount, we could shut down all the crummy public schools and put all the students into top-notch private schools.
If there's a problem with our schools, it's certainly not that we are not spending enough.
