Absolute equality is not attainable. Even 2 men never get the same wage/package, because it is not possible to measure exactly and objectively the amount of employee contributions to the business. I am sure you have seen unhappy employees because they thought they weren't appreciated enough, or resentful ones that thought the college with higher pay wasn't doing good job.
In most companies employee share of health insurance is the same regardless age or condition. But some people use a lot more of care then others, in some cases the difference is paid by the company. Do you want to count this portion as a compensation too. In one word, life is very complex and it's not possible to make it absolutely equal or fair. From the other hand, by making something equal, we usually make something else unequal. What is the best approach? I think, fine tuning is the way to go. I already told you about regulated systems, top down command systems are not the best ones.
As you see, my reasoning is pragmatism. Agree?
