There are many differences, is this a difference that will reverse a historic trend of world powers rising and faliing, of waxing and waning?

Will the diversity within the US enable it to pull together as a nation, overcome infighting, and out innovate China with it's plethora of phone and EV types, overnight pprototyping, on demand cheap bulk bespoke pharma production, etc?

> Is there a historic world power as diverse?

Rome?

Is there any legitimate evidence to this being a benefit?
