I love plays, musicals etc and I was recently thinking : there's clearly a huge amount of theatre shows, TV etc happening. And presumably there must be a limited pool of actors given that its reputation of being hard to make a living from surely puts many people off who would otherwise want to try.
Obviously many people will not be able to have a big part but why are so many actors unemployed often compared to other jobs? Are the same people being cast again and again for nepotistic or other reasons? Are there other explanations?
