The Central Bankers of the world don't seem to have learned their lessons.
Capital controls in China, Demonetization in India, Inflation in Venezuela... Bitcoin looks poised to succeed even further.
In most cases, the central banks are operating under instructions from the politicians who want power over the populations of their countries instead of freedom.
in most cases central banks control politicians
its a much higher hierarchical structure than the goverments are
but I agree the main idea is to keep the populace under control and keep the modern slavery system in check
I'd disagree that Janet Yellen controls the politicians.
Perhaps it would be more accurate to say that the same forces (whether people - subtle or overt- or misguided, immoral anti-liberty, authoritarian ideas) that control or guide the central banks and politicians want to keep people under their control.
The same ideas have animated that crowd for centuries (probably millennia) and the goals are to control the people to keep power and wealth to themselves.
