I've got a question for the BI fans that I haven't seen addressed before: The U.S. is a huge country, with wildly varying costs of living. Will a UBI be adjusted for regional costs, or will it be a simple flat rate? I can see problems with both options; with the former you'd encourage people to stay in (or move to) more costly regions, and with the latter you'd either be paying someone in Salina Kansas above the median income as UBI, or you'd have people on UBI in Chicago, Oakland, and NY still unable to pay their rent.
