america rules at invention. we invent pretty much everything tho 
Pretty much everything of any significance for the past few hundred years was invented by Scotsmen.
Best engineers in the word too.
Why else do you think the chief engineer of the starship enterprise was Scottish (ok a Canadian Irishman who could murder a Scottish accent).
And groundkeeper willie in the Simpsons. A man who can wrestle wolves and win.
And all from a population of 5 million.
