lol. It isn't, because it doesn't. The traditional elites were a lot more powerful back in those days than they are now - largely because they have the resources to game a complicated tax code.
Absolutely ridiculous, Gustaf. Power is precisely and exactly the amount of money you have. If you have more money, you have more power. They have more money now, relative to their subjects.
But you yourself, I imagine, would agree that most wealth is inherited and not earned in the form of an annual salary, correct?
True power wouldn't even be subject to income taxation.
