The US technology advantage is in software, hardware, biotech/pharma, AI, some advanced robotics (China is leading in general robotics), quantum, aerospace, military, medtech.

Competitively the US does well in energy tech and agriculture tech. The US is #2 in wind power, #2 in solar power, #1 in nuclear power, along with being the world's biggest oil & natural gas producer. The US industrial rail system is also an epic scale marvel, while its consumer rail system is pathetic.

It's definitely not elite in most infrastructure (including electrical plugs).
