I wonder if we need to introduce some sort of Career Support Centre in each town where young people claiming UC have to turn up every day as if they were going to work, so that they get into the routine of getting up and getting out of the house at a certain time, but once they are there, they can get help with job applications/CV writing, attend skills sessions (social skills, interview skills, IT skills, other work skills etc), access mental health support if they need it, maybe go to an in-house gym, access learning opportunities or help finding voluntary work etc. If they are on a confirmed course or voluntary placement, or attending an interview, then they are excused, but otherwise they have to spend the day there as if it were a job. And if they don't turn up, they lose a pro rata from their benefits?
I realise that this kind of facility would cost a fortune to run, so maybe it's not practical, but it would be a genuine investment in the next generation and it could end up saving the state more in the long term if these young people could get their lives back on track - in welfare, healthcare costs etc.
It's probably completely unworkable in practice but just an idea!!
