Indeed. “Used to” is the key observation. In the wake of WW2, the U.S. had both dynamism and the ability and will to act collectively. This combination led to rising standards of living, the space program, Silicon Valley, the internet, etc.

The U.S. economy is still relatively dynamic, but the will to collective action has completely failed.

Europe can act collectively but lacks dynamism.

What point do you think you're making? That's not the question. You're just repeating the same obvious geopolitical comparison everyone regurgitates these days.
