A free market economy is a complex system that, like most complex systems, is scale-invariant and thus exhibits power laws, including in the distribution of wealth. This makes it robust to random failures but highly vulnerable to targeted attacks on its most connected nodes. Democracy is one such targeted attack, transferring wealth from the minority to the majority of its nodes.
I would rather live in a dictatorship where my interests align with the dictator’s than in a democracy where my interests are opposed to the majority’s.
