In 1944, when he wrote his book, Friedrich Hayek noted that the crimes of the German National Socialists and Soviet Communists were, in great part, the result of growing state control over the economy. As he explained, growing state interference in the economy leads to massive inefficiencies and long queues outside empty shops. A state of perpetual economic crisis then leads to calls for more planning.
Socialism, in spite of its manifest failings and Hayek's warnings, refuses to go away. Wannabe socialists are thus destined to learn not from history, but from their own mistakes. In the meantime, ordinary people suffer.
To give just one example, between 1999, when Hugo Chavez took over as President, and 2016, average per capita income in Venezuela rose by 2 percent. In the rest of Latin America and the Caribbean, it rose by 41 percent. A similar story can be observed in Zimbabwe. Robert Mugabe, Chavez's erstwhile friend, has been in charge of his unfortunate country since 1980. Since then, Africa's income per person rose by 48 percent. In Zimbabwe, a socialist dictatorship, it has declined by 25 percent.
