"Human beings act in ways that are motivated by economic rationality, and will always seek to maximize profit"

your model has something of an explanatory gap

The science agrees that people are generally not motivated by economic benefit, especially when it comes to anything that involves thinking (e.g. writing).

The only area where economic benefit seems to motivate is mindless scutwork.
