We closed 50000 factories in a decade, and that's Ronald Reagan's fault? The turn down in factory work peaked in the 70's and started down before he was in office, and it has done much much worse since long after he was in office. Even in Europe most products are made in China, where I'm pretty sure Ronald Reagan had no real effect. Sure there are things we can do to help, but, come on, stop blaming politicians. The world is changing because of technology, and if you try too hard to stop it, you'll end up making things worse.
Case in point, robots are getting better and better, and we have 3D printing on the rise. Before too long, everything will be build by 3D printers and robots. It will be easier to have these factories locally, so they won't offshore production, they would just setup smaller factories nearer to the places where the products will be delivered. Then there will be only a few, very technical, manufacturing jobs. There are even working prototypes of giant "3D printers" that can build houses with working electrical and plumbing. More and more, jobs will be about creativity and specialized service. If you think it's better to legislate to stop change, you'll just make the world worse, then you'll blame others for the problems.
