You have moved the goalposts.
> I don't think you've ever been poor.
You shouldn’t jump to conclusions - there are many people on hn from other countries where having access to a thrift store defines you as relatively wealthy.
Either way, if you look like a hobo on your livestream setup, then people are likely to judge you.
I wish the world was less judgemental, but you don’t get to tell others how to be, so you have to live with how they act, and sometimes that means playing dress up. Sometimes it is
a sign of respect for other people’s opinions - some people really care about how you dress and that is OK.
Edit: also if you are obviously needy, then are you sure you can’t find thrift stores that will give you stuff for free? The best stores are run by volunteers who just want to help people.
