In 2016, the Federal Reserve reported that nearly half of all Americans would not be able to cover a $400 emergency expense without either borrowing money or selling valuables.
...So, it seems, a modest UBI really would help cushion families' financial security.
A low UBI would also have significant ramifications for America's financial sector, for the better of many Americans. It is no secret that it is expensive to be poor in America. Financial institutions make a significant amount of money every year by taking advantage of people who are unable to make ends meet in the short term. A low UBI would substantially diminish many Americans' reliance on exploitative financial products, saving billions in fees and interest payments on top of the cash payments themselves.
Two products that would be directly addressed by a partial UBI are overdraft fees and payday loans.
Postal banking would also address some of these issues, but like the girl in the taco commercial says, "Why don't we have both?".
