That’s the title of my latest piece in The Guardian. There are two key points

First, in terms of effective tax rates and tax paid, any means-tested Guaranteed Minimum Income can be replicated by a non-tested Universal Basic Income, and vice versa

Second, for a number of reasons, it would be better to begin by expanding access to an adequate Basic income (in Australia, the Age Pension is an obvious benchmark) rather than starting with a small universal payment and then increasing it to a level sufficient to live on.
