The Rational Optimist (P.S.)

by Matt Ridley

The lesson of the last two centuries is that liberty and welfare march hand in hand with prosperity and trade. Countries that lose their liberty to tyrants today, through military coups, are generally experiencing falling per capita income at an average rate of 1.4 per cent at the time – just as it was falling per capita income that helped turn Russia, Germany and Japan into dictatorships between the two world wars. One of the great puzzles of history is why this did not happen in America in the 1930s, where on the whole pluralism and tolerance not only survived the severe economic shocks of the 1930s, but thrived. Perhaps it nearly did happen: Father Coughlin tried, and had Roosevelt been more ambitious or the constitution weaker, who knows where the New Deal might have led? Perhaps some democracies were just strong enough for their values to survive. Today there is much argument about whether democracy is necessary for growth, China seeming to prove that it is not. But there can be little doubt that China would – indeed may yet – see either more revolution or more repression if its growth rate were to fall to nothing.
