It's not that I disagree with you in large party, but I think the issue of distribution, and thus redistribution, is an interesting one. How much value added has Bill Gates created for the world? This is effectively unanswerable, because it's not possible to measure. So how does he have over 100 billion dollars?
Distribution (and redistribution) aren't really representations of real productivity so much as they are representations of power. And that is a much more sobering thought. Power is wealth, wealth is power. A society with huge wealth inequality is a society with huge power imbalance. And the current ructions, even particularly amongst the right, are in large part fears of disempowerment.
When we also factor in ownership, and that ownership grants power and lack of ownership denies it, we can think about Revnak's position. More and more of the world is owned, and the more that is owned, the more people have to effectively "rent" to survive. Many salaries jobs are in practice renting the means to carry out the work because the jobs could not be done with the space / equipment provided. More and more land is owned; these days we protect land from exploitation by it being owned, so even publicly accessible land, once commons, is now owned. And perhaps in some way, we outside the capitalism class are in fact just getting weaker and weaker.
