The "imbalance of power" can only be "fought" by eliminating the concentrations of power. This is not a capitalist vs communist thing,it is, at least, a human thing, as humans need hierarchy, and power ends up being held by the few. The Romans, the Ottomans, the Persians, the Qing, and many, many other empires all have had the same "issues". I am sure this "problem" goes back to antiquity.
