unless PeerTube finds a way to pay content creators
Google is a for-profit organization. Framasoft, which developed PeerTube, is a non-profit one. The only way to pay content creators is when people donate money to PeerTube and then PeerTube share that money with creators. Which is also difficult because there are no trackers to know internally who has more subscribers or which video has more views, etc. Internally as using a tracker, but you have to visit one by one every channel and every video to know its numbers.
To me, it seems like you and the OP resent US users for simply existing in an online space without putting forth any solutions to the issue. Are you sure you’re not trying to find ways to justify anti-US bias?
If you want the space to have more equal representation, why not produce high-quality content that appeals to your fellows rather than moaning about people who by your own admission mean no harm?
There is no need to read those languages. Translations are still a thing. I remember that, while on Reddit, r/Europe posted links in other languages, but OP provided an English translation. So, yes, you can post national news in your official language, whatever it is, and post its translation, and now you have an international community or instance.
But it seems I'm the only one who posts links in my official language (Spanish) on international communities.
