Americans aren't as stupid as you assume we are. We know often food like Chinese and Mexican is catered to us but the same happens all over. It's not like we're some special lazy garbage people. If you go to Spain and order Chinese, it's made to accomdate their tastes.
I dont think americans are stupid,we just don't grow up eating food that is interesting and don't get used it. we eat carbs, sugar, butter/cream with lean cuts of meat. it takes work to explore food beyond that, so it doesn't happen and we get watered down international cuisines
Just like how pho and bandeja paisa in America is accommodated for the American palette which would be why Americans (I'm assuming you are American) would prefer their version of the dish over the country of origin's version?
Furthermore maybe you like the Middle East's sushi more because the Middle East has no sushi legacy and can appeal to the Western palette more?
I agree that America can have incredible cuisine that rivals other countries, but that's sort of the article's point - the majority of America is still devoid of this excellence.
Plenty of options in LA for northern, Isaan, central and southern Thai between Western Ave and Thai Town, and pretty good ramen, soba, and sushi in Sawtelle, Little Tokyo or Torrance. Perhaps not best in the world, but not at all catering to American tastes and could rank above average in the origin country.
My larger point was that LA and NYC (and specific communities in other cities —SF, Houston, etc) have a subculture that celebrates true renditions of various cuisines as cooked by an self-sustaining immigrant community large enough to not require external validation by Americans lacking in food culture to stay in business. You have to get lucky in most of the rest of the states.
Thai food in the US is nothing like what you will get in Thailand. Average ramen in japan is better then US. Same for sushi. Mexican food drops off quickly the further you get away from san diego/tijuana. We just don't have the freshest ingredients for some of dished from places far away.
