It's not true that US or any other developed country have lost their manufacturing base. The rest of the economy has grown faster than manufacturing.
Developed countries have moved into high-tech, high productivity, more capital intensive manufacturing with complex supply chains. If you want to bring back low productivity products into your country, you must accept wage decline, slower growth and lowering quality of life.
You can prepare for emergencies using other means and using relatively small adjustments. Post-industrial societies have higher productivity than industrial societies. Turning the clock back is not a good idea.
