@dank69 , I'm flattered that you would think I even have an economic theory! I don't, other than that we should be more fiscally responsible. Generally that would mean tax increases AND spending cuts, like that will ever happen! It will happen forcibly at some point, though, as long as current trends continue.
Since you've been so insistent, I'll take a more direct stab at your premises:
Rich people are rich because they benefited more from the system that the government establishes and maintains
There is probably no way to know that for certain. We don't have a parallel control universe where all the same people operate, for instance, in a more anarchic or more totalitarian environment. So it looks like there's an unsupported assumption inherent in your premise that only government is responsible for an individual's success. My own, different assumption might be that many of the people who are successful (rich) in this society would likely be similarly successful in another, whether the measure of success was money, political power, number of mates, ears of corn, whatever. There's simply no way to control for the presumed benefits our government confers. Therefore I have to either disagree, or assert that there's not enough evidence to completely support your premise.
It is in society's best interest to prevent dangerously large wealth gaps. The point where the gap becomes dangerous may be up for debate but you must either agree or disagree that there is some theoretical point that it becomes detrimental to society.
While I agree with the addendum of your second premise, the devil is in the details. Proposed methods of prevention vary wildly, do they not? My focus would continue to be on enforcing equality of opportunity, which is traditionally where the left and right find common ground. But since this won't ever be 100% successful, the left wants to move ever more to enforcing equality of outcome. This might seem like a more direct and effective method, but it's one that has some moral hazards, to put it diplomatically. I don't think there is a consensus on what is driving the increasing wealth gap, but finding ways to attack it that could draw support from across the political spectrum is important, hopefully possible.
As to the rest of the stuff in your above post, it's OT and mostly personal. Best not to waste space on it.
