Consensus is that the aging of the Boomer generation will indeed create a massive patient load with lots of the typical conditions associated with the elderly--that's just a simple demography question. However, it remains to be seen whether or not this will translate into any pay increases, etc.
My guess is that it likely won't, since the strain on the system caused by an increasingly large pool of retirees will necessitate cutbacks to entitlement programs. Honestly, though, this is one of the most enormous challenges facing the developed world over the coming decades and nobody has any idea how it will play out.
