I don't know man, prepping to run a session can be a lot of time and effort. Between the rapidly rising cost of living and the very troubled job market, if someone can help pay their bills by DMing a few sessions I don't see a problem with it. People need to eat.

I think there's a lot of demand out there right now for more human entertainment. A TTRPG is a lot more personal than playing a video game, and people want that, but not everyone has a friend group that includes a DM.

I think a lot of what is currently happening is a consequence of the COVID years. People were isolated for long periods, and a lot of small businesses that provided social meeting spaces collapsed. Post-COVID, people want to go back to socializing but so many local restaurants and other such places shut down, and it seems like habits changed too. People don't go out as much as they used to, and there are fewer places to do it, so it's a lot harder to meet new friends as an adult.

At the same time, a lot of people lost their jobs and didn't get them back. They had to find other ways to support themselves and their families, and the rising popularity of D&D in particular (I think largely due to content on YouTube from Critical Role &etc) has created an opportunity for that.

The TTRPG space is changing for sure, and it's growing. I can tell by looking at the shelves in my local game stores, there's more and more books for non-D&D RPG games. Plus, there are groups like Legends of Avantris who are now producing their second D&D module, for which they've hired a bunch of artists, musicians and other creative people to help with.

I don't have a problem with the idea that the growing popularity of roleplaying games is producing more opportunities for writers & artists &etc to make a living.
