One of my goals is to convince people that even small differences in long-run growth can have a powerful impact on living standards and societal prosperity.
In other words, the economy is not a fixed pie. The right policies, such as free markets and small government, can create a better life for everybody.
And bad policy, needless to say, can have the opposite impact.
Very few people realize, for instance, that Argentina was one of the world’s 10-richest nations at the end of World War II, but interventionist policies have weakened growth and caused the country to plummet in the rankings.
Hong Kong, by contrast, had a relatively poor economy at the end of the war, but now is one of the globe’s most prosperous jurisdictions.
If you want more examples, check out this chart showing how North Korea and South Korea have diverged over time.
Or how about the chart showing how Chile has out-performed other major Latin American economies.
This comparison of living standards in the United States and Europe also is very compelling.
Here’s a simple guide to highlight the difference between weak growth and strong growth. It shows how long it takes a nation to double economic output depending on annual growth.
As you can see, a nation with 1 percent growth (think Italy) will have to wait 70 years before the economic pie doubles in size.
But a nation that grows 4 percent or faster each year (think Singapore) will double GDP in less than 20 years.
