Umm....sir, what's that got to do with anything? We are discussing civil airliners. I am discussing in terms of in-flight product, American airliners are on the bottom. Not that it necessarily reflects a country.
For example Ethiopia currently got the best African airline, but Ethiopia is still one of the world's poorest countries.
So my argument is even today, despite China being classed as semi-developed, many things about them are better.
Such as better airlines, better urban planning etc. Of course America still got a better quality of life, on average.
