I don't mean those aren't useful industries. I just mean that to the movie-consuming public, insider stories about railroads and steel don't have much relevance in today's economy.
I disagree.
IMHO those topics are merely being ignored by the radical left-wing Hollyweird movie cartel, much the same way they ignored The Passion of Christ. It is fashionable in Hollyweird to mention those industries ONLY if they can demonize them. I'm certain that there is pent-up public demand for a pro-industrial movie. Perhaps the market isn't as large as for movies that are faithful to Christian theology. But nevertheless, it is a legitimate market niche that Hollyweird is failing to service.
