As with any generational generalization, this is far from a useful question. There is a whole spectrum of Boomer personas. There are those who never felt engaged in their work or communities and just want to continue that in a life of as much entertainment as possible. There are those who have passion for growing next generations. There are those who have always been engaged and want to make a positive difference in their world, through or without paid work. There are those who feel they must continue to work in a miserable job or career just to survive.
Any organization wanting to engage the best in their Boomers need to do workshops with them to engage them in dreaming.
