Generalists vs. specialists, that's a tough one. Being a specialist in a relevant field might lead to significantly higher compensations. Of course, that is not the general case.

I don't see any possible multiplier in your article apart from: "Otherwise, you can do freelancing on the side, write a book, or start a YouTube channel, a blog, or a podcast" here we get to the exciting points: opportunity costs vs. risk. The risk is still very low as there are little to none costs involved (only time). But these are business models which at least have the potential to scale and reach a broad audience.
