  The contemporary concept of "the economy" wasn't popularly known until the American Great Depression in the 1930s.
  
  After the chaos of two World Wars and the devastating Great Depression, policymakers searched for new ways of controlling the course of the economy. This was explored and discussed by Friedrich August von Hayek (1899–1992) and Milton Friedman (1912–2006) who pleaded for a global free trade and are supposed to be the fathers of the so-called neoliberalism. However, the prevailing view was that held by John Maynard Keynes (1883–1946), who argued for a stronger control of the markets by the state. The theory that the state can alleviate economic problems and instigate economic growth through state manipulation of aggregate demand is called Keynesianism in his honor. In the late 1950s, the economic growth in America and Europe—often called Wirtschaftswunder (German for economic miracle) —brought up a new form of economy: mass consumption economy. In 1958, John Kenneth Galbraith (1908–2006) was the first to speak of an affluent society in his book The Affluent Society. In most of the countries the economic system is called a social market economy.
