Though interesting, there remains a large sticking point that is more of a 'second order' effect not often thought of: the effects on marriage and child birth:

Though interesting, there remains a large sticking point that is more of a 'second order' effect not often thought of: the effects on marriage and child birth: https://www.nber.org/papers/w23408?utm_campaign=ntw&utm_medium=email&utm_source=ntw https://www.nber.org/papers/w23408?utm_campaign=ntw&utm_medi... "There has been a well-documented retreat from marriage among less educated individuals in the U.S. and non-marital childbearing has become the norm among young mothers and mothers with low levels of education. One hypothesis is that the declining economic position of men in these populations is at least partially responsible for these trends. That leads to the reverse hypothesis that an increase in potential earnings of less-educated men would correspondingly lead to an increase in marriage and a reduction in non-marital births." Based on this (single) study, it is reasonable to hypothesize that UBI would have an adverse effect on marriage rates and would increase the number of bastard children. The societal norms that we have about manhood, family, and marriage are somewhat based on economic models and radically changing those models may introduce severe disruptions in our social norms and family structures. EDIT: Forgot to mention, the 'economic status' that men in these regions have is a relative measure. Meaning that the researchers found that the men were being judged based on their status relative to other men in the area to determine if they were marriageable. UBI, by definition, would level out the playing field. If the means then that all men would become more attractive for marriage or all of them would become unattractive is an open question that needs to be studied more before UBI would be implemented.
