Political-economic readings of "Capital", such as Harry Cleaver's "Reading Capital Politically" redefine exploitation as a direct control of worked time, unrelated as such to distribution. These readings are usually associated with the autonomist strand of Marxism, which focuses on production as the key economic site within society. These readings of "Capital" are typically hostile to economics as such, and consider the transformation problem unimportant because they see all social arrangements in capitalism (in particular, profit and distribution) as politically determined contests between classes.
