I thinking on this matter is don't stop, but slow it down. I don't think we should stop imports from China at all. I do believe that we should cut down a bit and start making our own products. We were a country built on manufacturing. What happened? Did we get lazy and in good times we decided buying cheap would be faster? This is a major reason the economy is where it is today, we stopped making and chose buying.
The problem is getting people who would do the manufacturing and there is a reason why it is in Asian countries like China. If the government cannot solve the manufacturing of goods that are imported every year then they will still need goods and product from other countries and even if they have manufactured such goods it will still be years before they can meet the demands in the market.
