With a widening gap, would such a device further increase the gap between those who go on to be the "have's" vs. the "have nots"? Would this introduce a more substantial barrier to entry for the upper class? What if the device cost $1000? What if it cost $1000/month?
What would happen to society if 50% or more of society was structurally unable to move up in the class system? There is unrest today (occupy protests) and the common perception is that it isn't even a big problem in the US yet. How bad would it get if people actually thought it was as bad as it is? And then what if it got worse?
