let's say the entire country got a $1000/month raise. What do you think happens to rents in San Fran since suddenly a lot more people can afford a place there?

What do you think people living in San Francisco would do if they received $1000/mo UBI, and their rents increased by $1000/month? Just sit there and accept that it made no difference in their lives?

What do you think they'll do when they realize that they can move, keep the $1000/month, and live a better life somewhere else? Do you still think they'll sit in San Francisco bemoaning about how nothing is changed, or will they move?

They can't move now because their job is in San Francisco. With UBI, they're more able to.

Average rent for a one bedroom apartment in San Francisco is $3058/month. if you're making 50k/yr in San Francisco you're basically living in abject poverty.

Now, here is for comparison a 4 bedroom, 2092 square foot two story home in Oklamoa City. Estimated mortgage on that property is $394/month.

So imagine that you live in San Francisco. Imagine that you're making $50k/yr, living in abject poverty in a tiny camped apartment, taking public transportation because you can't afford a car. Now, imagine that UBI kicks in, and suddenly you'r making $50k + 12k = 62k/yr. Now imagine that, as you seem to be predicting, San Francisco rents go up by that same $1000/month figure.

So you now have a choice. You can:

A) Continue living in San Francisco in abject poverty, with basically the same circumstances as before UBI, except you're handing your landlord the extra $1000/month.

B) Quit your job and move to that Oklahoma City house that's twice as big, and still have a bunch of money left over, and maybe or maybe not get that pays a lot less but allows you to live considerably better than the 50k/yr did?

Which option do you choose?

Assuming you're not an idiot, and you chose option B, and assuming that lots of other people are also not idiots and also choose option B...what does that do to demand for San Francisco apartments?
