The whole notion of a universal income is the stupidest idea in the entire history of stupid ideas.
It is not. The main arguments "against" it are ones based on misunderstanding of what it is. Viz:
when your income is dictated by Government.
My man, what do you think UBI actually IS?
The only way the government dictates your income under UBI is if you have none, which is exactly how it is now.
With UBI you get a fixed income from the government regardless of any other income you may or may not make. The idea is generally you replace a lot of the existing benefits (income support, pensions, the whole lot) which have to be applied for, administered, policed for fraud and etc with UBI, and you then bump the taxes a bit so people earning some target income basically see no net change, thereby ensuring that you don't just print money, and the overall change to tax receipts vs money spent is basically zero.
An interesting follow on is that you could shift from the somewhat complex tax system to a flat tax system effectively without leaving behind progressive taxation.
Another interesting follow on is you may be able to entirely scrap minimum wage and its enforcement.
Will it actually work in practice? Who knows, but currently governments are jumping through a lot of expensive hoops to achieve outcomes which mathematically drop out naturally from UBI and flat tax.
