Is there any other space where taxes are so inequitable as with property in California? Why don't they move to a more equitable tax scheme based on, say, what the district requires rather than what the home was bought for? I already know the answer, because nobody would vote for it. It is the same in Berlin, where I live. People voted for the Mietendeckel but the only group of people that benefitted from it are the long-term renters who already have all the house they need. Among the screwed: small-time landlords, new renters and new families who need bigger apartments.
