None of this happened or is a problem in the EU. You can test your kids with the sniffles all you want. And tests for coworkers that aren't yet vaccinated or don't want the vaccinated are not a problem either.
Same with the masks, N95 (ffp2 masks in the EU) are and were everywhere and cheap, despite the high demand. Hell they gave them away even when you had shortages in the US. It is amazing how when a government actually determines that something is in the public interest and makes it...it actually gets made, instead of depending on some company that might not see a long term profit in something.
The problem always comes down to the government in the US, where other governments have stepped in and went ahead with creating PPE because it was in the public interest.... even if companies didn't see a profit . Whereas in the US, you don't have that and the waves are still hitting the US market. It is stupid really, given how much the US could have accomplished but just didn't want to.
