One interesting aspect of the plight of the temp workers is, that this is very exactly the kind of market Marx did analyse. The temp agencies distribute highly standardized work assignments to the temp workers, who have no choice. (If they would qualify for McDonalds minimum wage jobs, they would probably prefer them.) In this kind of environment the agencies can only compete on price, since the specific assignment is determined by the customer of the agency, and this means they need to cut their costs. ( Notice the mention of 22 workers in a 17 seat bus, this represents a 29% increase in efficiency of transportation.) And this leads to the situation where the least decent employer sets the working conditions, since he can out compete the other market participants.
