You’ve defined away every country on the planet, since the U.S. has a bigger GDP of anyone else. I already pointed to a study that looked at every country in the OECD, and found a strong correlation between smaller government and higher growth. The same study then widened the sample size to 60 countries, and the relationship held.
The other study looked at transient factors (ie. not just the size of government, but economic performance as government was made smaller). It too found a strong correlation between reducing the size of government and improved economic performance. And the poor did better as well.
To me, this is pretty compelling evidence. I’ve certainly never seen any evidence that making government bigger enhances economic performance in the same way.
But you also changed the goalposts - I wasn’t strictly talking about the United States, but about the relationship between big government and economic performance in general. Your insistence that all evidence is irrelevant unless the country is as big as the U.S. strikes me as a variation on the “No True Scotsman” fallacy.
No, I wouldn’t say that. For one thing, Reagan barely touched the size of government as a percentage of GDP. It was 20.2% in FY2001, and only declined to 19.2% by FY1989. So right there, we can say that the Reagan era didn’t really affect the size of government and can’t be used as evidence that reductions in government size will improve economic performance. In addition, Reagan only managed to slow the growth of regulation,and never did reverse it.
That said, let’s go back and look at the economic conditions at the beginning and end of Reagan’s presidency:
1980 Economic conditions:
Unemployment: 7.1%
Interest Rate: 19%
Inflation: 13.5%
GDP Growth: -.3%
Government Revenue: 31.7% of GDP
1988 Economic Conditions:
Unemployment: 5.5%
Interest Rate: 7%
Inflation: 4.1%
GDP Growth: 4.5%
Government Revenue: 32.8% of GDP
In addition, median family income increased by $4000 under Reagan. After the 1982 recession, the recovery saw GDP growth rates over 7%.
I agree that the 1981 tax cut resulted in less overall government revenue and increased the size of the deficit. But there is no question that Reagan’s 8 years, which represented probably the longest period of reduced government growth and lower taxes, was also one of the best periods of economic performance the U.S. has seen. Considering that he started with an economy in stagflation, I’d say that’s pretty good.
If Barack Obama got anywhere near these kinds of results from the stimulus, you guys would be declaring an economic miracle.
As for income inequality, that’s your hobby horse, not mine. I made no claim that supply-side economics reduce income inequality, so I’m not sure why you injected it into the debate.
