It already happened mate, in fact globally! Content creation has become a new trend now among the GenZ and so on. And the amount that can be earned from content creation is huge. From I am from everyone is a content creator. They are literally building homes, buying sports cars, leading expensive luxurious lifestyles, even traveling abroad all with earnings from these. It's nothing new. In fact many people even regret why didn't they started content creating back in the days. The things that we referred to cringes made them millionaire.
Some of these content creators who are living flamboyant lives might be engaged in other activities. I know some of them in my country engaged in illegal activities like fraud and money laundering. Since they are popular and assumed to be rich, fraudsters could easily use them as middlemen to launder funds from criminal activities. My observations don't in any way mean that there are no content creators who make money legally.
