Well, you've stated nothing but facts as I see it. There is a generation based largely on snobbery, but it transends that- I've seen numerous retirees in g35s, for example- that is even more puzzling.
There is a subtle social undertone of self-loathing in America; nothing built here is ever the best- there's some sort of 'mystique' about foreign lands and their goods. Sure, sometimes the item is better, but more often it's just different and many times it's outright inferior. But it has that damned mystique ('I picked them up in Italy' - says nothing factually but everything image-wise.) To some.
This goes back way farther than the present era. I have a working theory (based on research) that it can be traced back to colonial days when we as a nation were peasant farmers from 'civilized' Europe. I've read accounts of discrimination and insult within the early automotive industry alone, where American-based manufacturers and individuals were 'not capable' of matching European standards/ practices/ innovation. Nevermind that it was the American industry that shaped the rest of the world's auto industries. Read accounts of Cadilac's '08 DeWar Trophy win for interchangable parts- the world's amazement was equally based on the feat as well as the origin of the feat. We have adopted the snobbery of other countries, and re-directed it back upon ourselves.
Regarding today, I am again forced to turn & point towards the media, where the tidal wave of imagery that wretched excess is an aspirational life goal is crushing & incessant. It's not common to find people immune to suggestion, capable to thinking for themselves.... couple this with the above 'foreign is automatically better' Pavlovian predisposition, and seeing a 75-yr old WWII veteran driving a rough-riding, 140-mph japanese sports sedan is best described as a sad wonder.
