Interesting.
A wizard has granted you a wish, but a very limited one. You may gain a sum of money equal to the profits from the next major thing from a franchise. Do you want:
Final Fantasy 14
Call of Duty ((Whatever, no idea what they're on here))
the next Bond Movie
D&D Next
See you'd be crazy to pick D&D Next, regardless of the quality of these various things. Whereas you could probably legitimately throw AD&D 1E in there as something that you might consider, adjusted for today's money of course.
The hobby is just very niche. It has a strong and active niche, but it's just a niche, and it's not breaking out of it.
If it's any consolation, wargaming with miniatures is in an even smaller niche
