> A lot of our “value chain” is bullshit.
No it isn't, productivity has to increase, that's why we constantly get rid of jobs that do not provide much value. People want more money, and the only way we get there is with more productivity (doing jobs that make more money).
> If and when China becomes twice as big an economy as the US, much of our “edge” in marketing, finance, and services isn’t going to mean squat.
China gets to 2X our GDP by doing what we basically did in the 90s, so you are definitely right! They will have their own marketing, financing and services. The only difference is that they won't need to outsource manufacturing to China (well, they are outsourcing it a bit now, but also investing tons in automation).
> E.g. how much “GDP” will evaporate overnight when American universities no longer have the cachet that comes along with being the best universities in America?
I don't know what you are ranting about, but I get the feeling that if I did know what you were saying here I would probably agree with you.
