I have to disagree with him, I don't think mini rooms are the problem at all. It's certainly more efficient to do it that way, but I think the problem is that television has become too expensive. Actors, producers, directors, production studios, are all paid way too much. The simple cost of producing a television show is out of control.

you state that the rooms are efficient, and that other costs, financial costs, are the issue.

barely talking about the same thing.
