Instead of stroking his ego by racing Branson to space, Bezos could personally buy each of these people a home in the Bay Area and wouldn't even notice a difference in his lifestyle. Tax the rich. Spend it on social programs.
Who’s Bezos supposed to buy the homes from? It seems like there is already a higher than average number of people living per house here, so distribution of housing is not really the problem. The total number of homes is too low. It would help if Bezos could build a huge number of new housing units, but that’s illegal (which is the problem).
If there was an extra 3-6% property tax, it would align interests towards construction and punish speculators.
