I think that Universal Basic Income (UBI) is inevitable as technology makes more jobs obsolete. When enough voters lose their jobs, they will seek political change. That change will stabilize when UBI becomes law.
People will then shift from finding meaning in their work to finding meaning in spending time with each other. Whether those people are mostly old friends or mostly new family depends on the affordability of housing. Raising children is meaningful work but it requires an extra bedroom.
I propose Parental Basic Income (PBI) as a first step towards UBI. Since the invention of birth control, many potential parents have chosen to reduce the risk of childhood poverty by not having children. PBI will create a future in which parents are confident that they can raise a happy family.
