So I just bought a house (condo actually) in Oakland and I have to agree.
There's a huge class of people who aren't particularly impressive, hard-working, or otherwise "deserving" in my admittedly-morally-loaded-sense of the term, who happened to buy a ton of real estate over the last 30 years, and are now earning eye-popping rates of return (20%+/year on millions of invested capital) owing to the combination of increased desire to live in city centers, and prop 13.
It's really shocking. If you look at most small towns in America, the wealthy people tend to be small business owners, successful professionals, and perhaps a few landowners. Here in the SFBA, the serious peninsula wealth is all tech (early employees and execs) and everywhere else it's landowners by a mile. Here in Oakland, restaurants are closing practically every day because this rentier class is bleeding them dry of any profit. Both directly through rents, and indirectly by the wages employees are demanding to live in an area where prevailing rents are 2-3k/month.
I wouldn't even be mad about this except that they're using bad government policy to line their pockets, and they're just shameless about it. It boils my blood. These people are just leeching off of the huge south bay productivity engines (Google, facebook, Apple, etc) and taking a pound of flesh by restricting supply of a necessary good. Their entire livelihood rests with the stubbornness of execs at the big tech companies to stay here and put up with it. These companies end up paying exorbitant salaries just so that this rentier class can line their pockets with what would otherwise be shareholder profit or personal income of employees.
