>“UBI lets all the poor people leave” is not convincing at all.
The value proposition for service workers in high-COL cities like SF is probably already bad. How would UBI make it worse? At least it'd be easier to move away from those areas. Maybe cities would have to pay serivce workers more to make sure they stay.
Rents are high in SF because there is extremely high demand for those apartments at high prices, because they allow access to high incomes. The value of living in SF for a random serivce worker is not increased by them getting a $2k UBI cheque, it is decreased. For the tech workers driving the demand, $2k a month is not going to do much to change the value they assign to housing in SF either way. So I do not see how the UBI cheques would increase demand, and therefore rent, for housing in SF.
