An astounding tale from Philadelphia that reads like something out of the 1930s.
The only weak point occurs when the author attributes, as many do, things like the 40 hour work week to unions rather than to economic development. That leisure is a normal good (i.e. people buy more of it, implicitly in this case via fewer hours, as their incomes rise) is really the only explanation required.
It's really quite easy.
