why bad economic theories remain popular

Steve writes in his Blog……Ludwig von Mises and Friedrich Hayek, the most prominent “Austrian” economists of the time, anticipated the 1929 stock market crash and correctly predicted the dire consequences of government attempts to artificially stimulate economic growth in the aftermath of the crash. John Maynard Keynes, on the other hand, was totally blindsided by the stock market crash and the economic disaster of the early 1930s. And yet, Keynes’s theories gained enormous popularity during the 1930s whereas the work of Mises and Hayek was largely ignored. Why was it so?

Keynes became popular because he told the politically powerful what they wanted to hear. In particular, he provided power-hungry politicians with intellectual support for the schemes they not only already had in mind, but in many cases were already putting into practice. Despite being riddled with errors, Keynes’ theories also appealed to many economists because the implementation of these theories would confer a lot more influence upon the economics fraternity. The fact is that in a free economy there wouldn’t be much for an economist to do other than teach economics. He/she would certainly never have the opportunity to be involved in the ‘management’ of the economy.
