Have been reading Baudrillard's Symbolic Exchange and Death, and want to know useful sources that take on such statements as:

"Today everything has changed again. Production, the commodity form, labour power, equivalence and surplus-value, which together formed the outline of a quantitative, material and measurable configuration, are now things of the past."

Am particularly interested in following arguments about the relationship between modes of signification and modes of production.
