Interesting, and also not that suprising. IMHO USA manufacturing has been riding on the 1970/1980 reputation of "high quality" while the corporate culture has canibalized quality in a race for "more profit" measure or success.
China does not mean less quality, they established themselves as the global manufacturing hub for most of the world's industries.
And the US has become extremely expensive to live at, which in turn makes manufacturing pricy, gotta pay the workers to live in the top heavy economy that it is nowadays.
I have not tried Eastman's saxes myself, but @skeller047 here has, and I know Bob Mintzer and Bennie Maupin did too and found no fault to them,....
