A really good video series is Hidden Secrets of Money, by Mike Maloney. In a few hours, you can learn how the world works, and really understand it (even without formal financial training etc). For years, I did YouTube videos on the topic, and got to know Mike's team. He invited me to dinner in Vancouver a few years ago but I wasn't able to make it. Very smart man.

Playlist for all 10 episodes:

First episode on its own:

Episode 4 is great as well. Much of the dialogue in that one echoes discussions I had with Mike and his team. I'm not credited for it, but my words and ideas are all throughout that episode.

I think it's worthwhile understanding this stuff, because the world is literally based on it, and it is the reason behind everything happening right now, including C19.
