and they would need to be supervised, and trained, and insured, and that would all need to be administered, then theyd need travel/food expenses, and to be recruited, and given most of them wouldnt want to be there, policed somehow
far more expensive then slinging someone 60 quid a week wouldnt you agree
seen as unemployment seems set to stay quite high for the forseeable lots of people - maybe as many as 2 million would be forced into this kind of unpaid labour at massive cost both to the state (which couldnt afford it - thats why they're currently scrapping the workfare programmes that do exist) and the individuals concerned who are unlikely to be learning any new skills and are likely to end up stuck doing manual unpaid labour for a long time at huge cost to the people who were previously doing that labour fopr a wage and at massive profits for the bosses who would no longer have to pay minimum wage for unskilled labour
it is, in short, a fucking stupid idea
