The UK pilot will recruit 360 people in England and Wales. Half will continue to receive their current level of support, while the other half will receive extra financial assistance, albeit not directly. The charity Greater Change will hold and spend money on behalf of participants to ensure that their benefits payments are uninterrupted.
So the homeless person is not given cash. The charity is given a cash fund to spend on an individual.
This one fact diffuses most criticisms of this scheme, but it keeps getting reported with clickbait headlines.
UBI has to be funded by taxation on the rich. If you give Mick 2k/mo but tax him 5M/mo i think you're coming out ahead, and you're avoiding all the bureaucracy of deciding who does and doesn't get the 2k... Which would be large, complex and prohibitive.
I'd rather not set a precedent for it being means-gated. Some people who don't need it getting free money is an acceptable tradeoff to ensure that everyone who needs it does get it.
Don't get me wrong, giving money directly to those who need it most is a good start, but in isolation it will not go far to resolve the issue - people need housing, a support network, empathetic and accessible healthcare, some fucking stability and security.
Also - knowing how bad, by design, our benefits and homelessness "support" systems are, how neoliberal our government is, and how much worse they're already aiming to make them, I am extremely sceptical of this being applied without those it's supposed to help having to jump through a million impossible hoops, and somehow, some rich person ending up with a multi million pound contract for something or other.
Here's hoping it provides at least some real relief to a few people while it lasts, but yeah, I'm not pinning much long term hope on this.
