I can’t help being suspicious. Was it blocked on purpose? And if so what reason?We’ve seen so many magic tricks over the decades. Need higher Oil prices? Discourage international shipping? So more products are made domestically in each country?
Ya know, living standards and prosperity and tax receipts would be higher in all countries that produce their own goods as much as possible. Note the shortage of Chips. Masks? Why should “select” countries have monopolies on simple home made products? I can see various countries importing what they don’t have like Coffee or Rubber.
All the Indian Tribes each made their own arrow heads and wampum. I’m certain the Apache didn’t farm out Bows and Arrow work to the Comanche. 🙂
