Saving on bureaucracy is a frequently made argument that I have never seen supported by a quantitative analysis. Do they exist? Such a claim seems untrue on its face.
You can't eliminate the welfare bureaucracy with UBI because:
- You won't want to be giving free money to literally everyone, only people within your jurisdiction. So you still need to figure out who those people are and whether they're authorised to receive UBI.
- It will act as even more of a magnet for illegal immigration, so you'd still need to spend on border reinforcements. Same problem as they have now in Germany and Sweden: lots of people turned up who can't work and sit on welfare forever. If you don't stop this it's in reality a policy of giving out enough free money to live by western standards to the entire world, which isn't how it's being advertised.
- You still need to deduplicate everyone and ensure people can't register for UBI over and over.
- You need to stop people creating fake identities to receive UBI for people who don't exist.
- You still need to ensure UBI stops being paid when someone dies, even though families and friends have strong incentives to stop the state finding out about a death.
- You still need to decide how much the UBI is, how much it should change, and whether the amount should vary by location. What's plenty for someone in the countryside may be considered insufficient in the city.
- You still need to track where people live, the moment you give way on the amount being adjusted regionally, which you will because the sort of people who most enthusiastically support UBI are all-in on the type of "fairness" that invariably means not treating people the same. Or are they going to advocate for a single income tax rate across all earning bands as well?
- You will need a huge rise in taxes to pay for this, meaning tax evasion and avoidance will also go up quite dramatically. You'll need to bulk up the tax bureaucracies to handle this.
UBI is just a modern rebranding of what in the 20th century was called the socialist utopia. People tried it, it doesn't work. That was Russia at the start of the 1900s. UBI advocates today seem to have forgotten about all that, but they're re-treading intellectually dead ground.
