Externalization is highly desirable to _all_ interests. The interest of manufacturers is self evident. The interest of environmentalists has a level of indirection; without the frictionless externalization available to manufacturers the process of feathering our domestic environmental regulatory nest that has been cruising along mostly unimpeded for decades now would face a great deal more scrutiny and resistance.
As it is many domestic manufacturers are mostly indifferent to the regulatory state; they have no problem with the US evolving into a giant national park because they have a perfectly good alternative.
This isn't some abstract concept. As recently a the 2016 election I recall video ricocheting around the right wing echo chamber of Trump opponents at Portland protests pointing out that the last thing they want to see are those 'dirty factories' operating in the US again, employing deplorables. Every single one of them was armed with one or more Asian made portable computers, but that sort of hypocrisy never registers.
