I've seen people use UBI to mean "employment insurance" but that's misuse of the term.

From wikipedia: "A Basic Income would vary with age, but there would be no other conditions: so everyone of the same age would receive the same Basic Income, whatever their gender, employment status, family structure, contribution to society, housing costs, or anything else."

So it's not a small amount of money to do nothing, but just an "extra" small amount of money coming out of either welfare budgets and/or additional taxes.
