This is a similar problem that is happening in many professions.
Boomers are in many of the professional jobs and haven't left much room for younger professionals just starting out. Young professionals have had to go to other countries to find work in their professions or work in non-professional jobs.
With the weak economy and lost retirement funds, Boomers will have to either work much longer than planned, or just retire and hope for the best.
This will leave an experience and leadership void in many professions that is not being planned for and addressed.
