Assuming your point is that US universities are huge drivers of economic growth then that doesn't explain how China is growing far far more quickly than the US.
You could argue that China is experiencing 'low end' growth and isn't yet hindered by not having any 'top 10' universities. I'd counter that by saying that the UK funds universities very poorly (and also caps fees) and still manages to have 3 of the top 10 universities. If China wanted to build the best universities in the world they'd probably just do it, as they have the expertise and the money.
> relative lack of political corruption
True, 17th in the world isn't bad. Could do better. China scores 100th so they are behind on that.
> and where, by simply having kids there, they immediately become Americans
You might need to explain what your arguement is here. If you mean that it's easier to naturalise your family once you've immigrated then I'm not sure I buy that as a significant driver of GDP.
If you mean that it's easier to emmigrate to the US than to elsewhere, then that's demonstrably false, and has the potential to get even worse because some folks in the US think Donald Trump is a good idea. Try applying for an H1B visa, even as a highly skilled individual (with a corporate sponsor) it's a nightmare.
> I don't think any other country is close along many (and certainly not all) of these axes.
Plenty of countries are ahead of the US on both corruption and acceptance of immigration. Just look at the stats.
Take Sweden for example. In the 90s Sweden took 84,000 refugees from the Balkan states, and now they're taking another 65,000 from Syria (I think the US took 10,000). Sweden also freely allows immigration from anywhere in the EU, ranks 13 places higher than the USA on the corruption index, and has great universities and free higher education for all.
Take the UK. The UK ranks better than the US on corruption index (14th) and has 3 of the top 10 universities in the world, with only 1/5 of the US population. Admittedly we're being dicks about immigration at the moment, but I'm not convinced any more so than the US.
In short I don't think I buy your argument yet. Feel free to have another go if you want.
