> But I think it’s a cultural shift that is much older and tracks better to the decline of traditional sources of values (community, cultural groups, religion, etc.) and their replacement by the easily understandable dollar.

I think about that in the complete opposite direction. I think the dollar displaced traditional values. The cause I'd attribute would be our increasing reliance on "reason", especially short term cause-and-effect "reason".

Most of my perspective on this comes from "Dialectic on enlightenment", which I can recommend if you can stomach an incredibly dense and boring book.
