There is a nice discussion of MI in the context of rat choice marxism by Jutta Weldes in Theory and Society, 1989. She shows, in contrast to Eric's last message, that it is not a question of whether or not structures "make" people do things. Rather, the issue concerns the ways in which structures do or do not have an ontological status apart from the practices that produce them, and in turn the ways in which they enable and constrain practice.
