It does have left wing messages but it is still a great movie.
People of need were willing to work hard and rely on themselves to survive. They did not feel entitled to anything more than a honest day’s wage. Nothing like today’s profession victims poverty pimps.
The saddest thing, at least in my opinion, about Steinbeck is that he was a truly gifted writer, and a true pleasure to read, but he was simply dead wrong in the message he wanted to convey. Much like Ayn Rand, without question utterly brilliant and talented in some areas, yet has fundamental myopia in others.
