The presidency should not remain constant throughout history. It can’t stay as it always was and remain effective.
Everything in the universe evolves as a way to preserve its integrity.
When we witness the evolutionary process, it is natural to experience some discomfort, since we don’t yet know what that process will bring in the way of change and how it will affect our lives.
To block that which we don’t yet know is like making a decision based on a coin-toss.
Although sometimes evolution occurs spontaneously, generally it occurs in the presence of a methodical set of principles, as multiple layers of conditions and needs come together to create a new, but not totally unfamiliar, path.
If through this process some integrity is lost, then the system will work to rebalance itself, by smoothing its own transition.
