Has that worked the last few decades? And don't just count "job yes/no", look at the actual job - prestige, quality, income.

The proportion of people in full time work is much higher than it was when people worried about mechanization eliminating all those not-very-prestigious jobs in the post-WWII period...

My comment was pretty short - yet you managed to ignore a major part? Looking at statistics telling you that now both adults in the family have to work to home ownership to private debt levels doesn't support your story. Look at the number of dual-income families, for example.

Is there any income quartile in any developed country that has less prestigious or lower real incomes per full-time worker than the equivalent in the immediate post war period? Disproportionate rises in house prices and growth in consumer credit and student debt are consequences of a region having access to better employment opportunities, not worse ones.

Yeah, if you assume that workers never go on welfare, the argument falls down.
