@RoboRev @scottsantens to get more into it, UBI solves a "demand donut hole" problem.

Housing is the quintessential example.

A large number of people in this economy make effectively zero dollars and the primary reason is that they have no place of residence.

In a capitalist system, it is very difficult to generate housing units for these zero earners, because there is no amount of rent that they can actually afford. And it costs a non-zero amount to put new housing units on the market.
