Can’t say I’ve experienced this myself (millennial). Maybe I’m the bad influence in my friend group? I’ve definitely turned down going to things because I couldn’t afford it. That said, when gaming at least, I tend to just buy the game for my friends as I want to play with them and don’t want them to have to worry about that cost. Games are, relatively speaking, pretty cheap so I view it comparable to paying for a night out, which is often about the same cost.
