It's tough on lots of people. Many are fucked, mentally or physically, or both, by 55.
The problem is the easy, low-grade jobs that used to be available have almost all gone. There really is no room for the Alf Ventriss brigade anymore. How you fix that, I don't know.
The Town Hall alone used to be stuffed with basic clerical jobs that many people could (in principle) have done at age 75. All done away with long, long ago, because of computers and 'efficiency'. The railways were similar. I can remember when Belle Vue Station employed about 6 blokes. No one now. Work is high-pressure and demanding, and you need to be young and fit. Or at least fit. The modern way is to sweat people to death and then leave the state to sort out the casualties. It's unsustainable.
