Something is wrong if we isolate the well-being of labor from the social effects of firms. Some firms are financing technological innovation, others are financing idiotic advertising or trying to patent the letter 'g'. some restrict output, others try to maximize it. Some degrade the environment, others' well-being depends on the opposite result. Some spend money on training and family-oriented benefits, others use modern analogs to shape-up systems. Understanding the basis for these differences is a far cry from fixating on "jewish capital."
The 'unifying element of the exploitation of labour' seems more like the process of systematic over-simplification, albeit one with a sophisticated philosophical framework.
