The US is broken. In the years after WW2 the US made tangible the American dream. It did so through by connecting incomes to improvements in productivity. Simply: If you do more work per hour, your income should go up (see chart).
The result was a decentralization of economic decision making on a scale never seen before in the history of the world.
It was AMAZING. Tens of millions of financially prosperous households making decisions on what they should buy and invest in. Most of what America still is today was built during that period.
The violent colonial era comes to a close through WWI & WWII. International industrial production was defunct with America as the last one left standing. The era of the economic empire moved forward. Apparently, it was a relatively short one.
