Its rare that nuanced problems have simple solutions. The problem is not that evil employers are oppressing helpless employees, at least not entirely. The problem is that making physical things requires physical infrastructure and investment at a massive scale. Things move slowly and barrier to entry is high. Conditions like that are going to cause a slower, less transferrable skill set just because few entities are willing to take the capital risk to develop that infrustructure so fewer entities exist.
