This is the current estimates of expected GDP growth in 2025:
"Forecasters Predict Lower Growth and Employment in 2025
The outlook for the U.S. economy looks dimmer now than it did three months ago, according to 36 forecasters surveyed by the Federal Reserve Bank of Philadelphia. The forecasters predict the economy will grow at an annual rate of 1.5 percent this quarter, down from the prediction of 2.1 percent in the last survey. On an annual-average over annual-average basis, the forecasters expect real GDP to increase 1.4 percent in 2025, down 1.0 percentage point from the estimate in the survey of three months ago."
I don't know about the others but I certainly do not think we are seing the demise of the USA. We are just seing is a passing of the torch from one generation of billionaires to the next.
