The article's thesis seems to be that concentrated ultra-wealth is largely the "product of law" on the one hand, so lacking corresponding laws on the other end is unbalanced. Up to a certain point, one can try to make a case that one's accumulated wealth is the product of their own work. This is a simplification, and usually wrong, but let's go with it. Let's say that your first ten million is because you work hard. Let's say your next ten million is because you were in the right place at the right time. Let's say your next ten million is do to good choices you made before you realized how important the choices would be. Now let's say your next ten million is due to... uh... more hard work. And the next ten million too! At some point, one has to admit there's more going on here than hard work or a good idea. The article lays out that above a certain point--call it the fifty million I laid out above, or go twenty times that and call it a billion--a large part of your accumulated wealth is the direct result of laws and legal protections, and that set of laws is currently unbalanced.
