Has any one actually read this book, and can confirm how substantive it is?<p>You see a post with a title like, "<i>Study by MIT Economist: U.S. Has Regressed to a Third-World Nation for Most</i>", and you naively assume that the link will take you to... a study. By an MIT Economist. With actual data, about how the average or mean American has recently crossed some number of economic metric thresholds.<p>Instead, it's a book review. Really just a collection of mushy factoids (e.g. social mobility is lower today than it was just after WWII)... and political talking points worthy of a Facebook or Reddit comment (e.g. rich people are awful, and putting criminals in jail is racist).<p>Is the actual book a bit more data-oriented, or is the whole thing just ideological comfort food?
