Eliminate or marginalize dissent and you've deprived the system of critical information. Lacking a wealth of information, the system becomes a monoculture in which the leadership is free to pursue confirmation bias, focusing on whatever feedback confirms its policy mandates.
A system that suppresses dissent is fault-intolerant, ignorant and fragile. Any event that does not respond to centralized, rationalized policy creates unintended consequences that throws the centralized mechanism into disarray. Lacking dissent and redundancy, the system piles on one haphazard, politically expedient "fix" after another, further destabilizing the system.Though in Ireland's case, our elite still seems happier suppressing dissent than listening to it.
