Also what no one ever wants to admit is that this kind of system can only be carried out for so long before it collapses on its own.
If you start filling a million gallon wine glass on top of a bunch of small glasses, eventually you'll just crush and destroy everything at the bottom.
I like to imagine it as constructing a building. We keep building higher and higher, trying our best to place the richest at the very top and ever higher floor. To make it work, we keep taking building material from the foundation to build the penthouse. As the penthouse becomes higher and higher, heavier and more lavish, the foundation becomes thinner, smaller and weaker.
At one point we'll have an absolutely beautiful penthouse for a handful of people, resting on a very thin foundation that will eventually fail, fall and destroy everything and everyone.
