There's truth to this post but overall I think it's pretty naive. In a capitalist system the world belongs to those who own and have spare capital to invest vs. those who rent. Being very good at creating things is a potential pathway from renter to owner, but so is being very good at maintaining things, or managing people, etc. Anything which you can be paid a lot of money for will do.
You could be an author or an artist or something else, and have far more fulfillment in life than making 10x working at a job that you're good at but that doesn't bring you as much fulfillment.
