The next generation of retirees will be the following EXCEPT

The number of Americans over the age of 65 is expected to double between now and 2030. [24]This next generation of retirees will be the healthiest, best educated, and most affluent in American history. But many of them won’t have a retirement benefit their parents’ generation fought hard to get. It is something known as a defined-benefit plan, or "pension." Retired workers who have a pension continue to be paid a certain percentage of their highest annual salary—usually anywhere from one to three percent—multiplied by the number of years they worked for the company.
