I'll be potentially contentious and say I don't necessarily buy into the assertion (often put across in tv progs and by certain politicians) that only a very small percentage of people not working would rather work. I think, if people not working told the truth, the percentage would be higher than reported. Btw I'm not blaming them for not fully disclosing their thoughts on working, why would you, I'm just stating what I believe to be true. If someone is getting by on their benefits and is quite happy with their lot, why seek work? I'm not sure I would tbh. Yeah yeah you get all the rhetoric about it building character, being good for mental health, contributing to society etc. However depending on the sort of role being offered, the aforementioned benefits to working might soon wear off, let's be honest.
I think what gets folks backs up is the fact a high percentage of the population aren't exactly happy in their employment. I'm sure a study x years back found 70+% of us would rather be doing something else as a career, sad really. In that sense, although we're not all wage slaves in the traditional sense of the phrase, it can be asserted we are slaves to our work as we need to keep the money coming in.
I further think this, understandably, is what gets folks hackles up when schemes like this are suggested i.e. looked on as free money. It's a case of 'I have to work (maybe in a job I hate) why shouldn't you?' Many of us would like to sit back with the free time to pursue more creative activities, however we need to keep doing the 9-5.
