Watch the one invented by Milo Farnsworth, in Idaho.
How will you get to other places without our planes?
Kitty Hawk is in America. How will your gliders cross the channel without power?
How will you beat infection without penicillen?
Sulfas and other antibiotics. Incidentally, penicillin was not "invented" by Fleming. It was discovered by fortunate accident.
How will you have any appreciation of language without Shakespeare?
Shakespeare predates America, just as Aristotle predates Britain. How will you have any appreciation of music without jazz, blues, country and rock?
How will you have electricity that hasn't been invented?
Electricity wasn't invented, however, Ben Franklin did much to advance the early knowledge. And what good will electricity do Britain, without Edison's inventions?
How will you eat a hamburger, pizza or french fries without us?
Potatoes are American, and it is likely that pizza was invented in NYC. Ground beef on bread? I bet someone here would have thought of it, eventually.
Correction: Philo Farnsworth, not Milo.
