Let this be a lesson to learn for western democracies to not put all of their eggs in one basket. Diversification, localization and strategic globalization of the supply chain should be at the forefront of the issues to be discussed, ratified and acted upon after this pandemic is over. When one country manufactures 90% of world's goods (not accurate, to make a point), while the top 1% gets their bonuses for increasing profit margins, this is what we have. We've lost skills, we've lost our stance to manufacture things in our own homeland. It is depressing, deeply worrying and feels like the entire world has been gutted out by one country. Just to make it clear - think about this scenario - what would happen if one country made the food for the rest of the world? (Thankfully, we don't, but it can happen). What about pharmaceuticals? (Unfortunately, 90% of the world's generic drugs are made in Asia, primarily in India who in turn depends on China) [1].

Edit: I just realized that some of the startup and entrepreneurs around the world are on this forum, if you'd like to get into manufacturing, want to learn about more abstract concepts of manufacturing, I implore you to checkout: Manufacturing Planning and Control for Supply Chain Management reference book - https://books.google.com/books/about/Manufacturing_Planning_...
This book is absolute gold. Manufacturing is like playing this game Factorio (google it) but in real life. It is an exciting field ripe for innovation, many very hard problems and unlimited potential (and a lot of risk as well).
