How long before these sectors are unable to perform their function and the consequences have real world/daily living impact?

The workers who do not wish to be vaxxed at this point most likely will not comply and will walk. Has this entered into the managerial classes calculations? I doubt it, as at the moment they are pretty high from the power grab.

But time is not on their side, as the effects of the experimental vaccine become more pronounced and difficult to explain away (as does its impact on the health of the population). Add in the variance of different approaches that work better (ivermectin) (no masking) in other countries and the narrative becomes very hard to maintain. When they sense that they do not control the levers of power (they do not realize that they currently do not and they/we are running on inertia), it is then they may become dangerous to personal liberty and freedom. Cue Australia.

I don't think our ruling class here has the will. They have more guns and most of the money, but they have no heart or vision. Think of the true legend tyrants in history and in caparison these fools have no game. That does not mean they will not at least give it a go.
