I think the problem is that there are a significant number of people in the UK who are incapable of work. Of following instructions, of deferring to people in authority, of dealing with stroppy customers, turning up on time and turning up every day they're scheduled to work.
Years ago, people with limited skills went to work in factories - boring, repetitive but you earned a good living. Those jobs are no longer available. Plus the whole turning up thing is now problematic.
So what can you do. We can't send people to work houses any more. So as a country we need to give them money to live. I do believe the benefits system has been cut to bare bones. There probably are some people who get more than they're entitled but there are always chancers
Just like there are millionaires who don't pay their fair share
