That means the dilemma of the 21st century isn’t how Earth will feed an ever-growing population, but how the world will deal with a potential mass rebalancing of population via migration, an altered wealth-and-people equilibrium, in a world where technology is making the movement of peoples easier than ever. Clearly, the richest countries will be able to replenish their populations with immigration across the 21st century — if they choose. (A 25 percent ratio means there are four workers for every retiree; a 50 percent ratio, just two.) I don’t think you need to be especially pessimistic to regard that kind of transformation as incompatible with stable democratic governance. It’s among the reasons you already have the rightward shift in European politics and why immigration restriction will be a winning issue for the foreseeable future in many European countries.
