Good post JessM.
Durhamjen thanks for the links. Maybe you could say something like 'here's an interesting link' or somesuch rather than use the word 'need' which some people have interpreted as patronising.
I hope I'm not being patronising making that suggestion 
I too feel sorry for the young these days. The idea that all they have to do is move to a different part of the country to find work holds many flaws when it comes to the badly off. I know people who can hardly afford the bus fare to go and sign on, let alone travel further afield to job interviews. And where are they to live, especially if housing benefit is stopped for the under 25s? Even whilst they are getting HB deposits are needed, not to mention finding a landlord who will take in a young out of work person.
Incidentally, I had to do a lot of moving about for DH's job before he retired. I didn't like it. We never knew when we would be told we were going somewhere else, or where that somewhere else was likely to be but there was usually a radius of 150 miles. Hard to settle in a new neighbourhood when you know you may have to move again in a couple of years.
Financially there was no problem though. All moving expenses paid and a bridging loan provided to help us to buy a house before we sold the old one.
My father grew up in South Wales, an area considered deprived back in the 1930s as it is now. There was a scheme where young Welsh lads (dad was 16) were given apprenticeships in the Midlands. They were helped to find accommodation and generally quite well taken care of. Dad was just about to go back home because he couldn't settle when he met my mother and stayed. Not many apprenticeships about these days though.
