I'd be very interested to see the impact of baby boomers on the distribution of wealth.

Remember: (1) wealth tends to be correlated with age and (2) baby boomers make up a much larger percentage of the population (i.e. age distribution is not equal).

If you have a large bolus of folks moving through their careers, the graph follows the typical wealth trajectory. Right now, baby boomers are at or near the peak of their wealth.
