Those YouTube videos are arguably one of the best there are about economics. The lecturer is Steve Keen who wrote Debunking Economics. Those lectures are more or less his book and the then some. So every single one of them is worth watching if you want to understand real-world economics.
Steve has put the whole lot up in a playlist. You can find it here: Steve Keen's Behavioural Finance Lectures.
Enjoy and happy epiphany!
