Labor Regime Change in the Twenty-First Century sets as its task to assess the validity, in light of current economic development, of the epistemology structuring different historical interpretations that see unfree labor as incompatible with capitalism.

Challenging this, Brass argues that Marx accepted that, where class struggle is global, capitalist producers employ workers who are unfree.
