A Universal Basic Income could endanger vital public services in favor of a meager income. Money for just the UBI would likely not be enough to cover safety net needs such as housing and healthcare. Support for those things could be taken away to make way for the UBI in a limited government budget.
With so many of the jobs paying less and less, as time goes on, compared to other sources of income, such as real estate, investments and retirement, the concept of a UBI is appealing. Problem is, it may not be the best way to provide for people's needs.
Housing assistance, universal healthcare, affordable college and good transportation might be better ways to supplement low wages than just writing everyone a check.
Seems like wages, from work, are declining as a percent of the total economy; influences of things like automation, globalization and wealth discrepancy.
One ought to be able to hold a job that is still needed in society, daycare work; for instance and live adequately. Maybe even raise a family; if so desired.
UBI would be one path to this, but probably not the best path. A strong social safety net might work better, in my opinion. Also in the opinion of this article.
