You’re still just generalizing your experience in a way that implies that you actually know what most of middle America is like, when you don’t. And having lived in Poland doesn’t somehow prove that you do.
I’ve lived in the US for over 20 years and have been to more than half of the states, including all of the east coast, west coast and large parts of the mid west. The states I haven’t been to are way more rural than the ones that I’ve seen. If I had to guess I’ve probably seen more of the US than 95% of Americans.
I’ve also done road trips through large parts of Europe and can tell you that none of it is littered with strip malls, parking lots and houses on streets without sidewalks.
