At the very least, medical supplies and drugs manufacturing will get pulled back into each country. The 3M spat between Canada and the US makes it abundantly clear that in a time of true crisis, you can't even trust your closest friends when something terrifying happens to the world like this pandemic. Whether it means all manufacturing will move away from China or if it means that they will spread it globally, is an…
To be honest, I don't understand what efficiency gains this kind of globalization was supposed to bring anyways... A factory in China is just as efficient as a factory in Spain or USA. Obviously, cheaper workers work for less, but that's not exactly efficiency , (1) more a question of fairness, (2) can be done domestically (low-cost immigrant workers) and (3) there's plenty of cheap workers worldwide, not just in Chi…
This is why a factory in Spain or the USA is not as efficient as one in China (or vice-versa). Institutional knowledge has to be built up over time. You can't just start a factory in a place with no skilled labor for it. It's going to be way too expensive.
Just look at the US and compare to the EU. The EU has very few influential (or large) tech companies. The US has many of them. There's clearly some kind of concentration going on there and some of it probably is due to skill and thus efficiency. It's not that individual European developers are necessarily worse, but rather that as a collective (for some reason) they don't produce the same results as Americans do. I imagine that the same applies to factories.
