Ella, while Hoover began as an American company, that brand of vacuum became so popular in England that they very often referred to the act of vacuuming as "hoovering". I don't know if they still use the term, but I knew some who did back in the 60s.
If you've already read about FDR, his appointees, and his opponents, then you probably know most of what is in Shlaes' book. I think the title and cover are a bit deceptive. There is a lot about the TVA and its' opponents, some narrative about Tugwell's farm communes, the "war" on big business, and people like Insull, Eccles, Ickes, Mellon, Chase, Moley, and Frankfurter. I can't say I saw anything "new", but the book did fill in the gaps in my knowledge about who was responsible for some of the programs and agencies that sprang up at the time and some of the court cases against citizens who didn't comply with the minimum wage law. I didn't know that Mellon footed the bill for the National Gallery even though he was being prosecuted at the time, nor did I know that a law was passed to punish big business by taxing "undistributed profits". Of course, that backfired. FDR changed his tune just before we got into the war when he realized that big business was in the best position to provide products for the war effort.
Wasn't there a book discussion about the book here last year? Too bad I passed on it at that time.
