Eliminating Prop 13 would at least fix some of the misincentives in the housing market so that senior citizens living alone could afford to downsize to a 1BR condo and free up the empty 4BR house for a family with 3 kids.
I think my Mom is typical: because of Prop 13, she can't move. Her property taxes on a new home would be 20X as much.
Due to this, she's kinda 'stuck.' She lives in a house that's larger than what she needs, but she can't justify moving. I think she'd love to "cash out" some of that equity, but she can't.
This is how we got reverse mortgages (which are horrible.)
More importantly, most of California's spending is not to drive growth, but to keep its head above water. Investment is one thing, but never borrow to pay operating expenses if you can help it.
The comparison with Venezuela isn't all that off the mark, structurally. Venezuela also spent dramatically on social programs and redistribution because it could, with an extremely lucrative source of foreign cash. When the gravy train dried up, the whole system collapsed, which is probably what'll happen to California when the tech & entertainment industries dry up (and did happen in 2001 in the wake of the dot-com bust). California probably has several decades before there's a reckoning though: networks of human capital like you have in Silicon Valley and Hollywood are difficult to move or replicate elsewhere.
