> An inevitable outcome of capitalism
That is why there were laws against monopolies. But some far-right activists proposed the idea of "if it is a monopoly is because is so good that people wants it". And they run with it. It makes no sense as all these monopolies are created by buying competitors not by being better. But as it helps the new aristocracy to accumulate power many sellouts are in favor of it.
This is exactly what made the feudal system so unhealthy and hostile towards innovation. Wealth concentration means power concentration that makes a few people so powerful that new and different ideas are violently attack from positions of power. Kings do not want better farming or better fabrics if it means that they lose the control over it. Kings value control over anything else, and we are entering a new era of kings, concentrated wealth and stagnation. We can change that, break all monopolies, redistribute power and let a dynamic healthy diverse economy rise again and bring its fruits to society.
