Started reading Keynes Hayek: The Clash that Defined Modern Economics, by Nicholas Wapshott (2011). Here's an interesting bit:

In The Economic Consequences of the Peace, Keynes had raised the perils of inflation running out of control in language that would be hurled back at him by Hayek and his "sound money" followers. Keynes was aware that the fixed relationship between currencies before World War I, pegged to the price of gold, had been overtaken by events, because governments had printed money to pay for the war. Keynes reminded readers that the undermining of currencies was an invitation to revolution. "Lenin is said to have declared that the best way to destroy the Capitalist System was to debauch the currency," wrote Keynes. "By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens." Keynes gave credit to the Bolshevik leader for his perspicacity. "Lenin was certainly right," he wrote. "There is no subtler, no surer means of overturning the existing basis of society than to debauch the currency." In November 1918, by Keynes's reckoning, "in Russia and Austro-Hungary this process [of printing money] has reached a point where for the purposes of foreign trade the currency is practically useless." But Keynes cautioned that "the preservation of a spurious value for the currency, by the force of law expressed in the regulation of prices, contains in itself, however, the seeds of final economic decay." For those like Hayek, huddled in winter coats in their apartments because they could not afford fuel, Keynes's warning rang true. (pp. 22-23)
