I think the video captures a past that was a reality for a few people. It's very monochrome (no, I don't mean b&w ). It was a much simpler way of life and I imagine a lot of us miss that. There are so many distractions now, so many ways to occupy our spare time, money, and attention.
I doubt it was idyllic though, there was a lot of unrest so where did that come from if everyone was happily living the Leave it to Beaver dream? And would an honest hidden camera clip have captured anything close to that? It was a little bit of propaganda, not much more.
