You don't know the same retirees I know. I know responsible retirees who were frugal in their working years, and now that they have a nest egg, now that their kids are financially independent, they're buying boats, beach condos and motor homes. Going on cruises. Spoiling the grandkids. There are several areas of the country whose economies depend on the spending of retirees.
People I know have already bought all this stuff on easy credit and the trill is gone. Nothing is the same as it used to be.
Simplification will be more the new fad for the boomers...mark my words and plan for it.
