While I agree with brainfizz that our dear Admin has perhaps misrepresented several inventions as being American, just off the top of my head I’ll spout…
A seriously interesting written constitution.
A market for other countries to sell their goods.
Inward investment and therefore jobs in smaller countries.
The moon landings. Space exploration.
The Marshall Plan, not to mention saving Europe’s asses in two World Wars.
The Moon landings. The Viking landings. Hubble. Space exploration in general.
The second-most prolific movie industry in the world, but in my language, and with an astonishing distribution network. And some of the best movies ever made.
Jazz. Bluegrass. Rock’n’roll. Hip-hop. The seeds of the dance music revolution.
Aaron Copeland, Samuel Barber.
Nike, Reebok, the Gap, Abercrombie & Fitch.
Friends, Seinfeld, Six Feet Under, the Sopranos.
Don deLillo, Garrison Keiler, Jonathan Frantzen, William Least-Heat Moon, Herman Melville, Edgar Allen Poe.
The turkey. Popcorn. The hamburger. The hot-dog. The cheeseburger. Coke. Tex-mex food.
And so on…
