That's just an idea. I just think it should not be part of normal government budget because it could increase goverment spending for usual stuff and when that's increased it hardly ever goes down.
It might be different because there's no BI yet. BI is simple so the rules can be written to be simple too. Like setting up fund and spending on basic income not a fixed amount but last years fund income instead so the fund never gives away more than it earns.
