When I was a young man, traversing the '70s in whatever post-hippie, pre-slacker mode I could manage, I made a substantial part of my living, such as it was, in a myriad of minuscule supply-and-demand gaps that have now largely closed. I was what antique dealers call a "picker," a semi-savvy haunter of Salvation Army thrift shops, from which I would extract objects of obscure desire that I knew were up-marketable to specialist dealers, who sold in turn to collectors. To this day I am often unable to resist a professionally quick, carefully dispassionate scan over the contents of any thrift shop, though I almost never buy anything there. Mainly because the cut-rate treasures, the "scores" of legend, are long gone. The market has been rationalized. We have become a nation, a world, of pickers.
There are several reasons for this. One has to do with boomer demographics and the cult of nostalgia. There are now more fiftysomethings than there are primo childhood artifacts of a similar vintage. Most of our toys, unlike the wood and pot-metal of yore, were extrusion-molded ephemera, fragile styrene simulacra, highly unlikely to survive the random insults of time. A great deal of the boomer's remembered world has been melted down, or crushed into unreadable fragments in forgotten strata of landfill. What remains, particularly if it's "mint in box," becomes increasingly rarefied.
