Freedom and income
There is more.
Mary Anastasia O'Grady writes in the Wall Street Journal on the 2006 Index of Economic Freedom, published today by the Journal and the Heritage Foundation. Here are the rankings. And here is Heritage's home page on the index.
As O'Grady points out, there is a high correlation between economic freedom and income. In the 20 nations classified as free, per capita gross domestic product is over $30,000. In the 51 mostly free countries, it's $13,530. In the 74 mostly unfree countries, it's $4,239, and in the 12 repressed countries, it's $4,058.
