A few years ago I heard the story of a west coast US firm who did driveways. Interviewed, the Company Director was asked what he would do when every driveway in California had been done, 'Well I guess we'll do garages. Or windows' he said '...doesn't really matter'.
It didn't really matter because the firm did not exist to do driveways, garages or windows. The firm existed to provide employment for ordinary Californian guys. I loved that. We exist to give jobs out. Nothing else.
Despite a bit of pressure to sell just one Michelangelo statue the Royal Academy say they have absolutely no intention of selling any works in their collection to save jobs. 'You heartless bastards' shout some. I guess once upon a time I might have agreed with them. I don't any more. Museums are collectors. Hoarders if you like. They exist to collect. They have thousands of things collected but not on view to anyone.
Malcolm Gladwell dealt with this question, although it concerned the Metropolitan Museum of Art in New York City, in his Revisionist History Podcast Season 5. Museums exist to hoard. They employ people to aid this aim. People are expendable; the collection is not. Harsh, but consistent.
