I wish that we had a tenth of the contempt for the landlords and homeowners that causes this as we do for the tech bros who are the symptom of the artificial scarcity.
The tech bros were not the ones displacing people, it was entirely the fault of landlords who raised rents, and the homeowners who are selling for record profits. It is this landed class that has turned what should have been a boon for everyone into a zero sum game. Tech bros don't profit from the displacement, they pay for it too, it's the landlords and homeowners that profit. Tech bros didn't put in place the current system where there's no more construction, either, that was put in place by the landlords and homeowners so they could profit from the massive increase in land prices.
Tech bros brought fantastic wealth from around the world to California, and with our gloriously high income taxes, and our taxation of capital gains as income, and we should have been able to redistribute that wealth to bring tremendous prosperity to all, eliminating homelessness, maybe even eliminating good chunks of poverty.
The people who set and control this system are not the tech bros. Go ahead and hate them for good reasons, being greedy, or being ignorant, for having ugly personalities or interests, but don't blame them for displacements. The displacement it 100% on the Californians that profited from it and the class-unconscious culture warriors that did not profit, but unwittingly and stupidly supported the capitalist exploitation of labor and the displacement of those with lower incomes or who encountered hardship.
