Back before mass production, people were often defined by their work, by their output. The things they owned usually either were things they hand made or were things other people made by hand. There was a weight, an infusion of soul, in everything a person owned, used, and lived in. Today everyone is a consumer and has to pick from the same selection of goods as everyone else; and because of this people now define their personalities by how good their taste is, or how clever, or how obscure, or how ironic their choices are.
