Is it? I doubt that. Most actors are low paid and receive infrequent work just trying to grind out a living...probably working other jobs in unrelated fields here or there to pay the mortgage. There are probably thousands or tens of thousands of people who are actors, but lead relatively uneventful, normal lives like the rest of us.
This is true, in a matter of fact sense.. I managed a jobsite in LA that offered a lot of 'regular' part-time jobs to aspiring actors & musicians. Like u state, a lot of them were grinding it out, only occasionally finding work as background extras, or small speaking roles, etc. But I noticed that a lot of the aspiring actors held similar world views/lifestyles as their more famous peers in acting. The overwhelming majority were transplants from more Conservative locales & families. They often resented & rejected where they came from, and held beliefs they were consistent w/the sometime extreme cultural-Marxism (& decadent lifestyles) of
Hollyweird. (I was with 'em on the partying part).
So I agree.. lots of actors w/'regular' jobs, and ordinary lives.. but still different psychologically than the relatively "uneventful" places they leave behind.
I'll also add, that probably less than 5% of the aspiring actors I worked w/were native Angelenos.. most of the actual neighborhood of native Hollywood (south/below the Hollywood Hills) is working class, unrelated to entertainment. Peace.
