Well that's the problem. This is what everybody thinks which is not true. The products coming from these "emerging economies" may seem to be cheap but they are not. They came at the cost of our social welfare program in terms of unemployment benefits, food stamps, healthcare that we have to shell out due to displaced local labour as a result of these cheap imports. There is the cost of our research & development cost for our intangible properties lost due to forced technology transfer and theft that happened when we did business in China. And now looks like our sovereignty is in jeopardy with many of these "emerging economies" developing advanced weapons and even nuclear arsenals so now we have to shell out even more cost in our military development, a cost that we could've channeled into other areas that need desperate attention such as education, mental health, public security, infrastructure and local city development. Many cities in America are bankrupt as a direct result of these "cheap imports".
So if you add all these costs together you can see, these "cheap" imports are not cheap. Next time, when you see a cheap gadget on Temu costing $4.55, remember they do not cost $4.55; the actual cost of that gadget is more like $40.55. It's a lot cheaper to buy local.
