Is this really a conspiracy? What if it is just a huge misunderstanding?
What if the real problem is that nobody understands the true nature of money?
What if the real problem is that nobody understands the significance of land?
Chartalism sounds close to the truth considering ancient egypt adopted a grain bank system which is a commodity standard that is not based around the control of the economy. After all, anyone who farms grains, can "print money" because grains themselves were money! If you want aristocracy to have power over the "legitimate" economy, i.e. the economy characterized by a high degree of specialization and quite specifically the division of labor, then having money that does not grow and shrink in accordance to people's activity, and exclusively obeys its holder, more specifically, those who earned their money in the past and have yet to decide what to do with it, is the easiest way to achieve that.
If you think about it, if the saver or land owner has complete authority over his money and land then he is transferring power from the past into the present and the future in a world that otherwise does not stand still, where growth and decay are par for the course.
Socially speaking, death is quite useful, it prevents the elderly from halting the progress of humanity. What if we put a stop to that? Now imagine a world where you need to acquire power once and keep it forever. Power doesn't die but humans do. Then suddenly, everyone will be encouraged to acquire power at all costs, the sooner the better. Everyone will be living their entire life in a rat race.
