I think as far as clothes and poor people are concerned, 1) there are less poor people, and 2) there are a lot cheaper clothes available than when "Op Shop" was a place you could go when you were struggling. There are still a few around, but most of the ones affiliated with a church/charity throw out a lot of donated stuff, and just stock things they know they can sell for a few bucks.
Though if my clothes are still costing 2-4x what you're paying then maybe I'm not as badass as I thought lol
