Earlier this week I wrote about how America is the envy of the world.1
There was plenty of pushback. Many Europeans pointed out we have plenty of other problems plus a far worse safety net than they do. Fair enough.
There were also a lot of comments on inequality, even though I addressed that in the piece. It is worth noting research shows 40% of the rise in income inequality has been undone since 2020. That’s progress you never hear about.

(1) Population growth. More people means more workers, which means people spend more, companies make more money, so people earn more, etc.
(2) Productivity growth. Workers are more efficient and productive with their time because of improvements in technology and increased knowledge/education.

When you look at population growth in the United States it makes sense economic growth would begin to begin to slow.
Here is the absolute population growth by decade going back to the 1940s:
This number has been relatively steady over time. However, as the overall population has grown, the relative amount of growth has shrunk.
There were around 130 million people in the U.S. by 1940. By the end of 2023, it was estimated to be more like 335 million.
Here is population growth on a percentage basis:
Relative to the overall population, America experienced massive growth in the 1940s and 1950s. It’s been on a steady
