The Vampire Economy: Guenter Reiman
The Vampire Economy, by Guenter Reimann (1939) is a rare and wonderful thing: a detailed account of how the Nazis crushed the private sector and hamstrung the economy with vast regulations, violations of property rights, inflation, price controls, and taxes.
It is now available in PDF, and also as a print on demand book.
The author emigrated from Germany and worked on Wall Street after the war. One very odd thing: Reimann was a member of the Communist Party.
