Sounds like a good book and a valid conclusion. It is a response to many who have argued otherwise.
I suggest that, over the long term, culture follows economics. Any people will shift from work to welfare if work is overly penalized and welfare too generous. The opposite is also true.
Having spent decades following “development economics”, and its failure to explain or solve anything, I am more inclined to think the opposite. Culture drives economics.
