I would argue that in no point in history has it been easier to make a living producing things that other's want to view than today. You can make a very high quality movie with an inexpensive computer or even a phone, youtube will host it for you for free, and, if people like it, they can watch it and share it with others. Youtube will even pay you ad revenues or let you sell your movie.

If your movie is only good enough that it takes massive marketing to become popular, then that doesn't work, but then you are in the realm of producing what others are told to like rather than what they will like and share with their friends naturally.
