There are at least two problems with this thinking. The main problem is it's not generally true. The system is created by the entire organization. The people who raise money and allocate capital, the people who set development policies and priorities, the people who design and assemble the components, the people who sell it to customers and negotiate service levels and the people who operate and maintain it all collectively built the system.
Another problem is that it encourages moral hazards. Not paying fair on-call compensation allows unethical managers and sales staff to reap short-term rewards and bonuses by oversubscribing customers, promising more than can be delivered and rushing things to market before they're ready.
If you want happy employees, treat them fairly.
