France’s RSA does not meet UBI standards that we’re considering in the US / California because the amount paid is so small. If you live alone with 2 kids, RSA would be 899€/month in 2022, far below minimum wage.
RSA is not only the monthly amount paid, the recipients also live in social housings paying next to nothing in rent, heating, healthcare and transportation.
A similar thing exists in other country like UK or Germany
A lot of things are cheaper when you have the RSA, but granted, it’s mostly leisure and optional things (museums, cinema, holidays at ucpa.com, etc). (ucpa.com is an excellent sports camp address for 18-40, by the way).
Not only optional thing. Metro/bus/tramway are nearly free for them. They also have reduced rate for utilities.
Granted it is not easy to live with 500€ a month, but you can get by.
