Love that you're getting down voted but we had something approaching universal basic income in my country trough wellfare plans that were not exclusive with each other and had super lax requirements (since corrupt officials would take a cut of them) and it resulted in a very marked increase in poverty and a very marked cultural decline in work ethic on the lower classes

Why work or study when you can just stay at home and get paid enough to survive if you vote for the "right" candidate. People love to dream about theorized ideals but reality is often more complicated
