In Australia, we've had a 'living wage' for a long time: the 1907 Harvester Judgment ruled that an employer was obliged to pay his employees a wage that guaranteed them a standard of living which was reasonable for "a human being in a civilised community" to live in "frugal comfort estimated by current... standards." It got changed in the 60s to the 80s, but the concept remains in union rates.
Most reasonable employers are glad of the basic union rates, as this stops their rivals undercutting them on wages.
My son changed direction at age 30, and decided to take an adult apprenticeship, as an electrician. His wage is extremely good for a trainee- he brings home between A$850(GBP 513) and A$1150 (GBP693) a week, depending on whether he's only been at TAFE (tech) or been working a little bit of overtime. They've even given him the option to go to university when he qualifies, at their expense, to do electrical engineering. I think the ethos of paying people a decent wage, and looking after the, has survived.
But then again, we didn't have Thatcher.
