I didn’t say the U.S. was the most democratic country in the world—I wasn’t comparing the U.S. to Norway or Denmark. But the U.S. achieved in the 18th century something that Germany, France, Spain, etc., didn’t achieve until the mid-20th century. That’s an achievement.
And the lack of universal suffrage back in the day doesn’t diminish America’s achievement. India and Bangladesh and Iraq and many places have universal suffrage but they’re not as democratic as the U.S. was in 1789. Getting to that point is the 0 to 1 of democracy. Expanding the franchise from there is incremental development.
