For shorts, no. Shorts make you famous though, and maybe create a market for your talents, (and your viewers feel good).
I'm not sure there's a market for movies either (you said it, the competition is "insanely good") but we're going to give it a try with "Tin Woodman of Oz" (TWO). I was actually involved in making and selling a movie before (which included 20 minutes of 3D), so I speak from experience. There is a tiny, independent, non-theatrical world market if you sell cheap enough. Getting to it is difficult, and you don't get your time and effort back in money BUT it does get distributed. How many people can say that?
I'd have to say that 3D is a labor of love - but there IS a slight chance of success for those who continue to push onward - like the people in this community. You're welcome to do a shot or two for TWO if you want, just to see what it's like working on a "real" production.
