The adult population is 36 million http://uk.ask.com/question/what-is-the-adult-population-of-the-uk

The number of people being put on universal credit is 12 million http://www.bbc.co.uk/news/business-15535949

The number of OAP's is approx 12 million https://www.pensionspolicyinstitute.org.uk/default.asp?p=68

This means that the number of working age people is 24 million - therefore half of all working age people are either out of work or in low paid or part time work. From what I can gather the half who are working are over working to make ends meet.  To me seems obvious we need to up the wages and share the work out fairly between all who are capable and ensure we look after the old, sick and disabled.
