Many older Americans want to downsize (and cash out on their homes), Marie Kondo’s approach is popular, but where will all that stuff owned by older homeowners go?

Auctioneers and appraisers, junk haulers and moving companies all seem to be echoing the same thing: The market is flooded with baby boomer rejects. And they cite a number of reasons our kids are turning down the possessions we so generously offer to them. They rent rather than own, live in smaller spaces, collect more digital than physical items and tend to put their money toward experiences rather than things…

Her kids also rejected three sets of formal dinnerware, including Haviland China; vast collections of Lladro figurines and Department 56 Christmas villages; as well as 3,000 Beanie Babies and boxes of soccer awards she and her husband, who both coached for many years, earned with their children.

The only offer she got on any of her treasures? One son wants her Hallmark Frosty Friends ornaments she’s collected over 37 years “because he knows how much they are worth.”

Two scenarios could develop:

1. There will be a growing market in stuff that older Americans no longer want. Perhaps many millennials or Gen Z do not want stuff from their parents but some other American will want it. It does not just have to go to resale shops; enterprising individuals and firms could shop all these items online to find buyers interested in particular niches. Perhaps this could even expand to international markets and be shipped in bulk around the globe.

2. Much of the stuff will simply be thrown away, particularly items that are more sentimental in nature. Some lucky owners will find people to take or buy their unneeded items but much of the rest will simply find its way into landfills. Decades of consumption will end in the garbage can.

I have not seen any estimates either way of how much money all of these goods could generate or how much waste could be involved (or a combination of both).

Also, consider the implications of such a change: younger generations do not take material objects from their parents and grandparents, creating a bit of a gap in a material timeline. Perhaps the shifting of wealth from generation to generation more often takes the form of helping to pay for housing or student loans rather than tangible goods. How does this change memories and collective understandings of the past?
