I do not believe it is possible to cut back on Chinese products by 90%.
Even your computer and your car have Chinese parts in them.
Even if you could cut back on Chinese products by 90%, you would have to get a second job to pay the difference compared to non-Chinese products.
Your food, clothes, shoes, electronics, office supplies, building materials,
furniture, rugs, car parts, jewelry, tools,cameras, computer parts, dishes, toys,come from China, so whats left?
There is an article in todays Ft Walton paper about someone who was trying to do what you suggested no Chinese & seemed to be no problem. It is a problem unfortunately. For example Chinese womens shoes 30 dollars, same American made 114 dollars...............................................
