Answer:
A stable system cannot be maintained in democracy, because that system needs no moderation and democracy is a moderating policy.
Step-by-step explanation:
Democracy is a policy established by the will of the people. It opposes authoritarian governance that has the control power emanating from one person, giving that power to the people of a region and allowing that people to make the choices of governance and established policies.
Democracy has a moderating character and for that reason, it needs to be installed in an unstable system, allowing people to have options of choice and through instability, to understand which option is better.
