It’s like asking why a button down colored shirt is different than a white shirt (even a white polo shirt).
Society, ANY society, automatically labels people based on externals.
And, believe it or not, you label YOURSELF based on externals.
The way you dress, look, phone shape etc…. has an automatic effect on the “class” that people (and, more importantly, YOU) view you.
Once you are a “smartphone” person, you start associating with, and acting like, that “type” of person.
Same thing with clothing. Etc….
I’ve seen this fist hand and it’s a FACT!
