In 1977, education was 27% of the California State budget. In 2008, education was 37% of the California State budget, it is now 42%. And the absolute size of the budget itself is rising. So in fact funding is increasing as a percentage of the budget and in absolute scales.
The only real recent drop was 2007-2008. There is plenty of money available to run UC prudently as a resource for residents...indeed, more than ever before.
Downvote all you want, these are UCs own numbers so they are true regardless of your opinion or angst.
