This is wishful thinking. People are not paid according to their productivity, although it is a minor factor. People are paid accordingly for a variety of factors including region, negotiating ability, charisma, job demand (the more a job is objectively helpful the less it is paid because people are willing to do it for its own merits), and network if they are commoners. If they are born into the ruling class or have amassed enough wealth to live through arbitrage, there is no requirement to produce anything other than the idea that you are productive.

The owner doesn't pay proportionally to their worker's ability to produce, they pay according to how little they can get away with since in order to profit it is necessary to minimize expenses. If two employees are important but the less productive employee refuses to work for less than a certain amount and the more productive employee is satisfied with what they're being paid, the less productive employee will be paid more.
