UBI is good on paper but far from enough. Without Universal Ownership of the State, UBI is easily removed by inflation.

A better yet more difficult model is universal basic resources (food stamp to exchange for packages, social housing, etc.). People can work X hours on these social projects after reviewing some training (e.g. training of plumbing to maintain the social housing apartments). This also gives them some meaning in life. Of course this will degrade in the future if there is no ownership of the state by the people, but I think it’s going to last longer.
