I haven't seen too many studies of UBI, but the ones I have seen usually had a pretty limited sample population (usually very low income to begin with), and the subsidy amount was pretty low. I'm not really sure what conclusions we can draw in total. I wonder if it would help more people choose to have kids and start families.

That being said, nothing helps if we don't loosen the regulatory constraints causing inelastic supply in education, healthcare, and housing.
