This is a couple years old now, but is the best discussion of why centralization fails, and why decentralization wins. Of course, anyone who has ever visited a socialist/communist country can testify, all things centralized eventually fail.
It really boils down to what you are pursuing… Freedom or Security. Socialism and all forms of centralism are the pursuit of security.
When one pursue Freedom, they wind up with both Freedom and security which follows at very little cost.
When one pursues security, they wind up with neither.
So on all levels of your life, and in all relationships with others, seek freedom, let others be free (within normal confines), and you will find security.
Great video in my opinion:
