My main fear is how this will affect renting and house ownership. Rents will probably go up as UBI comes into play and what’s left won’t be enough to save for any kind of down deposit. I doubt UBI will be enough for monthly mortgage payments in any case.
It’s already very hard to move past the renting stage, I imagine it will be impossible once on UBI.
The cast would be comprised of land and business owners. Again, it’s already almost the case, I just think UBI without careful considerations would amplify it.
