Call it whatever you like. I'm perfectly fine with my use of obvious hyperbole, and I have no plans to reconsider when I'm unconvinced that the misreading of it was sincere.

Claiming that life expectancy "fell for several generations" is a poor reading of the data. Most generously there was a period of stagnation predominantly caused by a combination of scarlet fever and rapid urbanisation.

More generally you're arguing against positions I haven't espoused and which I don't think even represent areas of disagreement. Productivity gains and social organisation are not opposing forces. The surplus from higher output made shorter hours, better pay, public health, and medicine sustainable, making it possible for labour movements to secure larger shares and better terms of that surplus. We live in an amazing world now, if you take a moment to stop and think about what actually matters.
