If ANYONE deviates by maximizing their own situation under a new, untested tax regime, then BY DEFINITION, prices MUST rise higher than the levels that you claim.
It is not me living in the stange world ... I EXPECT people to behave outside the parameters of the plan.
[For your scenario to come to pass, EVERYONE must have perfect trust, perfect foresight, perfect capital mobility and perfect fairness (and that's what the simulations expect, by the way.) ]
Nonsense. I don't rely on vendors to have trust or foresight. I rely on their desperation to hold market when faced with consumers that punish them for not underbidding their competitors.
It's a dynamic process that happens automatically every day in a free market. It is not something that relies on central planning, foresight, agreement, or trust.
