Both approaches aren't mutually exclusive. I give priority to what you and the article are saying, but once you realize that, there's no reason why it can't be complemented by a high paying job. 40 hours of work a week, if you manage to find something you (half-)like, is a minor inconvenience compared to the alternative of not being able to enjoy many of the things our modern world has to offer.
