The 'what happens about people who are shit with money' argument is a red herring. As pp have said, there will always be people who are shit with money, selfish, whatever. It is not a reason to not dismiss alternatives to the status quo.
This might be of interest. Am not sure when this vote is actually happening - probably by the end of this year according to other sites - and who knows if it will go through. But I think it's fascinating (and heartening) that in one of the richest countries in the world there is considerable support for a new way of doing things.
It isn't pie-in-the-sky stuff/crazy utopia wonderland at all. And it's not communism. The concept of a citizens income has historically had support from both right and left. Done properly, it would be fiscally neutral. And of course provision would be made for the disabled, carers, etc. Several manifestations of a CI also include stepped payments for children (eg birth to 5, 5-11, 11-18 etc), though it varies.

I think it's depressing that whenever the possibility of change is raised, it's shouted down by those whose main concern seems to be that people who they deem unworthy might possibly be getting 'something for nothing'.
I think the CI would be the mark of a more equal, kinder, happier, less venal society. But I know that's not what most people care about. Work, work, work, consume, consume, consume, and never let yourself consider the possibility that there might be a different way.
How much is enough?
