Is there a generally accepted name for the area of the economy occupied by buying or selling used merchandise? Is that it? The ‘Used Merchandise Economy’? I once thought ‘Underground Economy’ might be the phrase I sought but came to realize that term refers to transactions most people consider illegal.
I do a lot of shopping in antique malls, thrift stores, junk shops and used book/record/CD stores. Over the years I’ve contributed frequently to whatever that segment is called. The items found there, even if I don’t buy them for myself, are far more interesting than what you see in any modern shopping mall.
It probably defines me.
