Its not a false assumption. The world today is full of innovative products built with American capital and mostly American minds. If Americans want to do something then they have an rich pool of talent to do it well.
Sure on average, the population of the US is stupid, but that's true of everywhere.
Just because you sold your soul to an economic superspreader meme that allows your products and inventions to percolate with the rapidity of an influenza-herpes-ebola hybrid doesnt mean that the minds behind it are brighter than the rest of the world.
> built with American capital and mostly American minds.
I would say "built with American agency and commercial spirit", not minds.
Most of the things that we have were first built elsewhere (Germany being a prime supplier here with the mp3 or the Zuse), but turning them commercial was the input that came from America.
