The issue is that you’ve made an assumption about an entire culture based on your own external experiences, and when confronted with opinions beyond your limited view, you ignore them because they don’t immediately make sense to you.
Sounds familiar.
I’ve never gotten Costco socks, but when I was researching the best pair of socks to get for my dad, everyone was raving over them, comparing them to the Darn Tough brand. If they’re not holding up like that anymore, then that’s unfortunate because I was really looking forward to trying them out some day.
