The video sounds like one of those circular promotional things like the ones created by all sorts of financial and self-help gurus. They have books that give you an incomplete story but continuously talk about their seminars that they hold around the world that they push on the reader throughout the entire book. Then the seminars are more of the same thing, an incomplete story that does nothing but push their book on you. It ends up being just a big circle jerk, and the only information they provide in the end is basically just about having a certain mindset. Like having the right mindset will change your life lol. (There is some truth to that of course but often it's not why you originally bought the book).
Anyway, your synopsis of the video actually sounds interesting regarding reserve currencies and the rise and falls of empires. China as a rising empire has been talked about a lot and you can see it's workings all over the place. It has taken over the majority of global manufacturing obviously and I even suspect that it is the reason for the insane housing market in Canada at the moment, which is mostly due to foreign investors driving up the prices. They are playing a strong game right now that's for sure.
