Every generation has its own obsessions, and they assign meaning to things, like "learning equals earning."
It's not much different from me spending tons of time diving deep into computer programming, AI models, and gaming. I thought learning more meant gaining more, but really, it's just a form of self-indulgence that hasn’t actually made me any extra money.
So, I can't really say there's anything wrong with people spending on these self-help events. Everyone needs to find their own meaning in life. Life is tough, and having something meaningful can help us hold on a bit longer.
