Re: UBI - not a silver bullet, not a golden ticket

It has done so - not particularly well - at the cost of Byzantine complexity, poverty-traps, a fortune in otherwise-unproductive bureacracy, and so on. So, replace all that guff with a simple UBI, which will also simplify income tax by scrapping allowances (and potentially some of the rate banding - base rate may well rise to the same level as the next band, or more) and generally simplifying things so that people can actually see WTF is going on.
And how is the situation when people lose their job different under UBI than otherwise? If I lost my job with UBI, at least I'd know exactly how much I'd still have available (and it would already be in place); if I lose my job today I'd have months trying to figure out what I'm entitled to, quibbling with bureaucrats about it, and waiting for them to get round to actually starting to make the payments.
