England is a modern industrialized country with similar wage levels, and similar regulations that businesses must adhere to. This means we're at a roughly level playing field in trade. In fact the US may have an advantage here. Trade does have economic benefits. More exchange of ideas, easier ability to move and assemble resources as needed. More competition leads to more innovation. That was all correct. BUT what was ignored before was that when there are big differences between nations that can eliminate these benefits. When you have to compete between a nation where worker's rights are protected and one using child sweatshop labor the profits encourage companies to go to the one with few or no protections over the one with strong protections. Trade policy should be designed to ensure a more level playing field. Countries with similar conditions, which enables fair competition should be given free trade or at least trade with few restrictions. Countries like China which exploit their workers should have heavy tariffs applied (and even bans in the case that products are not adequately inspected for safety) to make up for their unfair advantage.
Trade with England does not benefit the US since they have nothing of value to offer the US.
