The last great economic expansion or at least economic reconfiguration was internet services (which of course is mostly distinct from financial services) and the US ended up with a very dominant trade position in internet services.
My purpose was to cast doubt on Rayiner's assertion that "Since the 1980s, the U.S. economy has become highly financialized. It’s disputed how much American economic dominance is real versus on paper today."
I was not commenting on whether the world would be better off if the US were less economically dominant.
If all US internet companies stopped existing tomorrow the world would be no worse off for it.
The internet infrastructure is great. Networking hardware is great. Private internet companies built on top of it? Big whoop
