I've been reading The Lords of Finance lately. It's been on my wishlist for about eight years now; I had thought it was about the choads that nuked shit in 2008 but no, it's about the central bankers and millionaires that knew, beyond a reasonable doubt, that the Great Depression was coming and were powerless to stop it.
The most interesting aspect, as opposed to Galbraith's gold standard on the subject, is that Ahamed lists prognosticator after prognosticator who saw the end coming years ahead. The popular press was absolutely about money-money-money but the writing had long been on the wall, and was effectively an inevitability pretty much as soon as the Germans invaded Belgium.
