In my home town a sanitation worker makes double the provincial minimum wage and gets benefits. That's an incentive for a job that has a low barrier to entry but undesirable labour.
The benefit of this system is that you can in fact choose this role instead of being assigned it based on the requirements of society. If the compensation isn't tempting enough then the employer will increase the compensation until it makes sense. That's how it's supposed to work at the very least.
If the current implementation isn't working then you address the issues with the implementation, you don't tear it all down and try something completely different.
