Makes sense to let other countries trial it and if it works then we can consider it. I like the idea of UBI as we wont need a load of public servants for a simple system that supports the needy efficiently. But I am not convinced that the price of everything will be adjusted up because everyone having a guaranteed value income could make that UBI the new zero (all prices factor it in and move up). Also it would neuter government vote buying which they wont like as they cant pander to welfare issues (or more likely they will move away from UBI to bribe their voters).
Of course to afford it would require everyone to pay much more in tax. Unless we are ditching other public services for it but that wont win votes either.
