Reaction I: Trillionaires behaving <i>how</i>? If they acted like competent, mature leaders, actually concerned about the long-term welfare of the 99.9999999% - that'd probably be fine. Vs. the behavior of modern mere-billionaires, which is far closer to "tell the fiddlers to play louder as I grab some more loot from the burning City of Rome"...not so much.<p>Reaction II: How much will dollars be worth, when there are trillionaires? Will that be enough to buy a decent house anywhere?
