Hollywood job pays on average 27K. (Using the numbers in the summary).
I'm not sure about the methodology in the summary, but if you look at the scale rates for most Hollywood entertainment unions you'll see the weekly rates even for entry-level job classifications will be around $2000/week. Actors are only a small part of the puzzle and they aren't really representative of the entire employment picture of the film industry. For every professional actor in the film industry there's gotta be a dozen people in behind-the-scenes crew positions.
Even then I'm not really sure how much more "broad" the App economy is, since it seems to be dominated by "star" apps, particularly in gaming, productivity and social networks. Also consider that Apple takes a 30% agency fee for all apps while CAA and William Morris Endeavor only take 10% of their client's salary, and even then Hollywood talent agents are seen as the acme of largess and venality.
