To be fair, that is true for car manufacturing and phone manufacturing in most cases. Whatever requires a chip basically, like GPU's for example. Because if you need to buy chips, you are going the giants like Nvidia and car companies and all of that, instead, you have to build your own, which costs 20+ billion dollars, and takes many years of R&D which you may never catch up.
So why deal with that business, when you can just get it from other nations for cheap, put low tariffs on those special items, and get it for cheap. Hell, some people around the world (forgot the nation, was it Thailand?) can get iphones cheaper than Americans. Because chips are near, factories are near, so it's cheaper that way instead of traveling all through many oceans.
I am unsure that what was that counterargument to, or if it's even counter argument as i wasn't talking about tariffs.
Because it still doesn't rule out the fact that rich people inside those economies get to buy better products, just like in your country. It doesn't matter if they get them cheaper in overall comparison to you. It's still very unlikely that poorest people would buy state of the art top-notch technology, when they can better afford cheaper models (if they can afford even those).
