Especially for me and Tex, Douglas recommends Bourgeois Dignity: Why Economics Can't Explain the Modern World.
I have to admit that the thesis statement makes it sound a lot like The Secret for Capitalists. If I were a betting man (and I am), I would wager that the author has formed this thesis by getting the correlation/causation of changing attitudes exactly backwards.
However, it would be unfair to render such a judgment with any finality without actually reading it. I forward it merely as an initial impression based only on her abstract and the associated press material. We should consider the arguments.
