And on top of all that you then have to knock out of the calculation those DMs who, while they are quite willing to run a game and think they are more than capable of it, are simply incompetent or worse; bad enough that nobody will play in their game.IME, Typically, about 4:1 overall, and for any given game system, closer to 6:1. And then, IME, about 1 in 5 GM's does so only because they can't find a game to play in, and when they do, quit GMing as long as they do. And only about 1 in 5 GM's prefers to GM over being just a player.
I find here there seem to consistently be enough potential players that we-as-DMs can to some extent choose who we'll invite in; which is nice, as my experience over the years includes some pretty grim players who I'd rather not have back. Flip side is not so great; that being there's lots of people out there who would like to play and probably be lots of fun to have in a game but who don't have a DM and aren't confident in doing it themselves.
