"The way to crush the bourgeoisie is to grind them between the millstones of taxation and inflation” is a quotation that has been credited to Russian leader Vladimir Lenin (1870-1924), but there’s no evidence that he ever said it. British economist John Maynard Keynes (1883-1946) interviewed Lenin and wrote something somewhat similar in 1919:
“Lenin is said to have declared that the best way to destroy the Capitalist System was to debauch the currency. By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens.”
“Its (government’s—ed.) fiscal policies grind him (citizen—ed.) between the millstones of excessive taxation and inflation” was cited in print in 1952. “Lenin said that the way to crush the bourgeoisie was to grind them between the millstones of taxation and inflation” was cited in print in 1966.
