My point was that the development gap is what lead to the current situation, not that it's just cheap labor that makes Chinese stuff cheap.

My point about maintaining higher economic efficiency is actually the same point you're making. How can the globe (not just the west vs the east) learn from the past and build for the future. We live in a magical world with translation services available to billions of people, how can we empower them to organize around the right ideas. How can we preserve culture and art while flooding ourselves with technologies developed globally? Who pays for security and research? Intellectual property law in general?

So many big issues and questions still need a lot of work.

I think Congress is actually the biggest obstacle to efficient manufacturing in the US. It is a body where the primary motivation of representatives centers around what they can get for their constituents, not what makes sense nationally. So any government spending (eg procurement) will actually tend to drive fragmentation as representatives fight for their states.

Take for instance the space sector. It is fragmented by design. By Congress. Not only is it spread all over the country, making collaboration expensive, time-consuming and clumsy: there are essentially six different federal space agencies of which NASA is just one. This is terribly inefficient.

I remember when reading about the Apollo missions it was astonishing just how much time they lost by different parts being built all over the US and then shipped across the country to be integrated. Utter engineering madness that was only made to work because one could pour immense amount of cash on it.

This is why companies like SpaceX was able to run more efficiently: they do a lot more in vastly fewer locations. Ditto for Lockheed during their golden years: Skunk Works was famous for having "everyone under one roof and within walking distance of each other". (That Skunk Works neither exists anymore, nor can it exist, but that's a longer story which is also about extreme inefficiency).

It is reasonable to assume that Europe wouldn't do any better. Or any setup where politicians are inclined to optimize for regional gain. You'd probably end up with the same political fights over who gets what if the EU were to push towards more of the kinds of manufacturing that you find in China.

We know we're inefficient and we have some idea of why. We like to blame factors that are easy to politicise or evoke emotion (environment, exploitation of the poor etc), but I don't think they are as important as people tend to think.

We just don't want to change. And there are legitimate reasons for that. Chief among them that we're uncomfortable with strong central control. (Well, we used to be. It only took a majority of republicans about a decade to turn 180 degrees on that question and prefer an all-controlling federal government dominated by the executive branch)
