That wouldn't be a 1% friendly solution though - too much of their wealth is tied up in land and equities. It might mean that landlords in the Bay Area couldn't collect rents of $6,000 a month for doing nothing. Most of that unearned cash would flow in to state coffers instead.
It's ironic, because the Howard Jarvis Taxpayer foundation (the group behind prop 13) tried to justify prop 13 by saying that raising property taxes would hurt the elderly. Californian voters believed them.

People believe them now too.
