You seem to have interpreted "have faith in your own country" as "have faith in the people who grew up here" whereas I interpreted it is as more like "have faith that the parts of the country's institutions and culture responsible for its excellent economic performance will continue to prove difficult for other countries to replicate".

Those two things are strongly overlapping. People are socialized into the institutions and culture that other countries find difficult to replicate.

Having seen American institutions up close I’m sorry to say that if you subtract the people who have bought into the American dream you’ll find that it’s educational institutions are unremarkable.
