If you insist on buying only equipment which is entirely made in the USA, you are going to live a life of deprivation. I am certainly not saying it is wrong to try, I do too, but I would not renounce to use a product if I could not find a home made one.
If your require 100 % local products, you will be able to eat and drink - although you will have a restricted choice - and that is about it.
I am not sure I understand that fixation on US made thermos bottles.
