Our economies, culture, the whole of our civilization is based on the assumption of population growth. Because, quite simply, that's how it's always been. We have never before experienced a reduction in the human population for any extended period of time. I wouldn't count the US out yet, it can easily augment its population with immigration. So can all the other developed countries. Anyway, regardless, making a currency with a fixed supply doesn't work under any scenario. With a constant or increasing population, you want to increase the money supply. With a decreasing population, you want to decrease it.
