Suppose you had gotten a room full of economists together in 1980, and made the following predictions:
1. Over the next 28 years the US would grow as fast as Japan, and faster than Europe (in GDP per capita, PPP.)
2. Over the next 28 years Britain would overtake Germany and France in GDP per capita.
And you said you were making these predictions because you thought Thatcher and Reagan’s policies would be a success. Your predictions (and the rationale) would have been met with laughter.
After showing how successful the US was relative to other countries, Sumner writes:
Krugman makes the basic mistake of just looking at time series evidence, and only two data points: US growth before and after 1980. Growth has been slower, but that’s true almost everywhere. What is important is that the neoliberal reforms in America have helped arrest our relative decline. The few countries that continued to gain on us were either more aggressive reformers (Chile and Britain), or were developing countries that adopted the world’s most capitalist model. (According to every survey I have seen HK and Singapore are the top two in economic freedom.)
