The way writers get more money is through notoriety, when you steal a writer's work without saying they made it you claim the notoriety for yourself and effectively get to steal future roles and credibility that would have given them money.

Writers build a moneyed career slowly over time, being paid for good articles isn't the point and isn't why they do it, they do it to build for future positions and security. In this lense it's easy to see that yes, it is literally bourgeois behavior to steal uncredited labor to build your own enterprise.
