How does this logic work when the next generation/incoming demographic is even bigger? Boomers aren't an isolated bloc of people followed by 20-year-olds. It's a continuous expanding number of X year olds every year. For specific USA numbers: There are 18.7 million 65-69 year olds. There are 21.1 million 60-64 year olds. There are 22.3 million 55-59 year olds. Etc... You can't have one demographic retire/die off and everything is cheap again -- because there is always another demographic moving right into their place all the time.
