@onepict So the question is either: How can we afford it, or how can we not afford it?

Scrimp on a few other budgets and reduce waste in a lot of other areas to all but cover the cost. Don't forget many people already get welfare hence 780 billion becoming more like 150 billion.

The cost of administration in welfare would also reduce quite dramatically, if it's automatic; no more DWP assessments. Most people are on PAYE too so the government knows how much money you make. UBI can be automated.
