In Alaska you have UBI and it comes from the state selling oil… where does the money come from for pie-in the-sky UBI?
People that use their money to invest (time or money) into good companies will profit more, people that use it for just consumption will remain low 'income'.
When companies succeed as a whole (eg move to all solar,robots,ai) all 'shareholders' will benefit. one of those will be the UBI program
