I intentionally delay my response back to you as it seems the subject seems a bit more direct to you. I don't want to rub you the wrong way unintentionally and unnecessarily.
That being said, your fair concerns are part and parcel of the deal. These are risks both sides can manage to minimize, but would be really hard to bring them down to zero, with zero here implies exported foods remain more or less at the same price, or better get cheaper, and imported foods are of acceptable quality to your taste.
But that's the part I'm a bit confused.
Everybody wants trade as they want it, pick all the good ones and reject the yucky ones; essentially making trade associated with a kaleidoscopic range of adjectives with negative overtones, like "unfair","disastrous", etc. In a way it reflects the amount of skin in the game I believe. It's the first time in history that a sizable portion of Western population feel the negative sides of globalization. Basically globalization is moving along a path Western nations cannot control 100% like in previous version of globalization, aka, colonization.
In the previous versions, weaker Eastern and other colonized nations didn't have any control over the process. Nobody heard or cared about the local populations' suffering.
Now East is slowly driving the globalization and gradually reversing the course in their favor. It's going to hurt them a little, but much much milder than what our fore-bearers suffered at the onslaught of previous globalization.
This is a long time coming.
That's a fair enough assessment of one aspect of the situation.
At the same time it is an opportunity to keep up the bar or raise the bar for a larger portion of the world's population in terms of food quality and availability. But things might get worse before it gets better similar to the path of renewable energy industries.
From the perspective of an average American this can't come at a worse time with the Trump administration's deregulation agenda especially the casting aside of environmental and pollution issues. American food quality is likely to decline significantly from that alone.
Add in the fatten profits first mentality that both directly and indirectly got Trump elected and importing food from China where quality control is worse, it's practically guaranteed that American food quality will decline.
China is indeed a huge market with huge demand especially for commodities like food and have driven up prices in other markets, there is no reason why it would be any different this time.
Though only one factor for now, it is an example of the quality of life things that will add up and eventually reduce the allure of being an average American versus being an average citizen of many other countries such as China to the point where people who the US desires will no longer see becoming an American or living/working in the US as personally beneficial. This is a core and unique pillar of US soft power that is being eroded.
I think the US has been making unforced error after unforced error strategically since the late 2000's financial crisis, mainly due to a self-serving elite who has corrupted the system and too much of the population. As mentioned by others somewhere in the forum recently if the US falls it will fall by rot from within just like every other empire before it. I'm still holding out hope though that this course will change.
