Perhaps you could take a look at the thread just woven on this list. The thread's name went "plagerism watch /LTOV/LTOP/Missing Marx". One side argues strongly that Marx's was a contradiction of Locke's theory. :>).

Jonathan Nitzan:
I'll try to clarify.
To exploit somebody is to take from him/her something that is "theirs." I believe -- and correct me if I'm wrong -- that Marx took from Locke the notion of ownership by virtue of creativity. The worker creates the product, which in turn makes the product "belong" to him/her. Now, in a commodity producing society the capitalist takes from the worker part of what the worker produces. For this reason, Marx says that the worker is being exploited.
