As a general comment, Marx wrote in a period when 1) productivity was much lower and the big problem was still making enough stuff, and 2) most labor was direct labor, so there was a direct relationship between labor inputs and product outputs.  Neither of those apply to the developed world today. Many of the developed world&#x27;s economic problems come from the fact that we no longer need many people to make the stuff and provide the services.  US employment in manufacturing, mining, construction, and agriculture is now about 14% of the US workforce.  In Marx&#x27;s day, 80-90%.<p>Marx wrote in an era when capital for enterprises was hard to accumulate. Now we have a capital glut, but a demand shortage.<p>Economic policy-making hasn&#x27;t caught up to this yet.
