Oh and let's not forget the many, many problems it has caused for the education system you so respect. Prop 13 is often named as one of the reasons why CA's public education system is under such financial duress at every level.
Why can't we just admit that we need far, far more housing stock, far, far better public transportation systems, far, far better infrastructure and that CA's unique property tax system has essentially stymied all of those efforts. I find if hard to believe CA wouldn't be better off without Prop 13.
On another note, this post strikes me as incredibly hostile toward anyone moving to California. "Stay away, this place is ours, and if you come and can't buy, then don't complain, because this place was ours first." "Oh, and you're a tech person, so bugger off, we don't need your kind anyway!"
Is the person who just bought property at market rate today more entitled to complain according to your metric? They will have paid more in taxes than the person who bought in the 70's cumulatively paid over all those decades within just a couple of years. Would they then be more Californian somehow? Entitled to more of the state's resources? How about those people who have rented here for 30 years? If you don't/can't own property are you less Californian?
