1. Were you just ranting or asking a question?
If the former, thank you for sharing.
2. If you spend most of your money on "electronics, textiles, housewares, and other disposable items" then you are very unusual. Most people spend most of their money on services (including housing and health care), food, etc. which are produced in the U.S. Imports constitute only $2.1 trillion out of a GDP of more than $14 trillion, and much of the imports are commodities such as oil and lumber rather than manufactured goods.
And even when it comes to imports, China provides only16.5?
Even if you ignore commodity imports such as oil and lumber, that means we get more manufactured goods from other countries than we get from China.
That you choose to buy the Chinese products suggests that you buy on the basis of price rather than anything else, so even if the same goods were made in the U.S. at a higher quality, you still wouldn't buy them.
3. Where do you get "again"? The only time the U.S. made all its own products was during the world wars, when it had no choice.
Whether you are looking at the colonial period when the colonies imported from England, the days of the clipper ships when the U.S imported from all over the world, including China, though the building of the Panama Canal (to help with international trade.), trade has been essential to the U.S. as to any developing economy.
4. It is the case that for many years the U.S. raised high tariffs against imports "to protect domestic industry",
but that was only justified because foreign companies were producing the goods cheaper and better.
If you are willing to pay much more for everything and give everyone in the world a much lower standard of living, then we could go back to those days of high tariffs.
