Do not know any big theories. My thinking could also be wrong too..
My concept is that, the rich would have to know how to take advantage of society resources in order to "make use" of that labour too, which in turns provides jobs for the poor. For this, the rich should be rewarded for the knowledge and courage on using those resources right?
If one day, this "area" of resources becomes diluted, no longer wanting to service the rich, I believe the rich would turn to other resources to ensure things goes on for them right. (E.g. technology taking over human resources) It is still the poor that loses out.
Lastly, big bosses are busy with getting hold of clients, ensuring proper mgmt of companies, expansion plans, this ain't easy either. So why is it that the rich must cater to the poor who only belongs to like 0.05% of the entirety.
Okay okay, what I said sounds sick, but I really think of it this way
