Maybe not rich per se (though some I know certainly seem to be), but I do think at least on here a lot of people do prioritize games, some even to the potential detriment of their livelihoods.
What I'm saying is I think the high end of the hobby does have a "trickle down" effect on the rest of it. ALL video games going up in price isn't some random thing - certain things have happened in the hobby that has garnered interest from previously disinterested parties. More people want games now than ever, and more and more are getting into retro collecting.
We even have kids taking an interest, not that they're necessarily buying the games up themselves. I know on here we actually have a relatively decent amount of teens, even if they're not particularly active. Kids these days, despite being brought up largely in a digital only kinda world, seem oddly interested in preservation. It'll be interesting to see how the now-teens feel about NES games etc. in the years to come.
FRANKLY I'm surprised to not have seen more stories about people LOSING their massive collections due to wildfires in the States and the like, but there's still time (are they still going?), and perhaps a discussion for another time.
