Maybe I'm naive, but my sense is not everyone streaming on Twitch is trying to make a career out of it. Even for those that are -- everyone starts somewhere. Hopefully those that aren't successful on first brush notice and realize that it takes more than simply starting a stream to build a sticky audience.

Also, there are many people out there who lead fulfilling lives without families and partners. Either way, I don't think you should pity people so readily. At best it's somewhat condescending and missing much of the complexity and nuance of what it is to be a human person
