Im my opinion, all employees in a business should receive about the same amount of money. Either someone is doing a necessary job and thus contributing just the same as everyone else, or that job is not necessary and then there is no need to pay someone to do it. There can some variance in the distribution and that might even be useful in some sense.

That said; I'm a syndicalist. I think that the people working in business should own that business. That way there's no issue of exploitation.

The capitalist model of economic progress allows too much inequality to creep in, something that in the long run is harmful for any society. It also allows of an unreasonable compounding of slight initial differences that then will explode into the madness we see today, where some individuals have more economic power than hundreds of millions of others - now that is unfair.
