The Western consensus reality has been able to persist longer than the Soviet one did mostly because it started with a larger base. Soviets were trying to manufacture consent out of nothing, Westerners could rely on 100% of the old money.
It's fairly clear that the Western consensus has deteriorated much from its peak, which occurred shortly after 9/11. The degeneration and random flare-ups of "opposition" movements is evidence of this. Directionless attacks against the status quo are symptomatic of a ruling class that has trained its populace to obey but can no longer effectively give them orders.
