I think that the boomers will go to their graves kicking and screaming. Medical advances will keep them alive longer than their parents. And they’ll use their money as carrots so that their children will take care of them. I don’t see how the boomers can avoid spending their savings. Boomers are already passing their money to the Gen Xers (early inheritance).
In my views the biggest demographic shift will happen in about 30-50 years when the Gen Ys come of age. We’ll have declining population at that time, unless we allow more immigration.
