Because there's no national structure for it - it would all need to be achieved on the state level given both politics and the different needs of different states. We have community colleges here but I don't believe there are almost any public certification institutions. Also because in almost the entire country there are no protections/contracts for workers being fired at any point for any reason, and also workers can leave at any point for any reason, companies have very little incentive to spend any money to train people. It'd be perfect for society to step in and provide these sorts of institutions but in our current political climate ANY outgrowth of government except to military is seen with extreme skepticism.
