Also China doesn't invent anything, they routinely steal secrets from my company and many other major industries in the US. For example if you travel on business to China you aren't allowed to connect to any Wifi networks except company-owned networks, because the government will spy on you and steal trade secrets. There are stories of employees taken out for dinner and drugged and they got their briefcase and laptop stolen. It's a rough world out there. The US still leads every other country in innovation.
