It's hardly a life of Riley at 72 quid a week but I think it would allow people some time out to develop themselves creatively. It's probably why the UK has and still does punch card above its weight in the arts, especially music. Some of the greatest musicians of the country have spent significant amounts of time on the role that allowed them to create music. Especially as there is a lack of jobs in this country. Maybe inflation, especially house prices, would be less if people had the security to leave jobs and try other things with a guaranteed safety net.
I do think there is a good argument for the citizen wage. Would allow people time out of work, at a very basic level of existence to educate, train and develop themselves. Let's face it most people hate going in to work for a job they don't like but are scared to make a change as most people are only a few pay packets from being g wiped out. I'm rambling on a bit but I do think something like the citizens wage would benefit the country and individuals long term.
