What we are seeing is an unprecedented combination of quasi-monopolies, rent-seeking, and an economy disconnected from real production of goods and services.
It has been called neofeudalism.
Unfortunately "capitalism" is a pretty ill-defined term. I wouldn't include "rent-seeking" as a characteristic of "capitalism" but apparently you do.
This makes it very difficult to have coherent discussions. For what it is worth, I think "rent-seeking" is probably a characteristic of all economic systems and therefore isn't something peculiar to "capitalism" and so shouldn't be used as a criticism of "capitalism".
According to what theory?
