Coming from the more well-off side, it makes friendships with people on the other side harder as well. By chance a good chunk of my social circle in college was less well off than me, and while we liked playing games together I got weird looks for buying shirts new at Macy's or Michelin tires. It just seemed to rub them the wrong way, like they thought I was trying to show off or rub something in their face even though I'm just upper-middle-class and buying what I saw as the best product for what I needed. It's not like I was showing up in a new Lexus or something. Some of them also expected me to drive them everywhere even though they had working cars of their own, and that got rather toxic after a while.
