The US is in for a little pain over the next few years but will be fine in the long run. There is a reason the Euro is crashing and the US Dollar isn't.
Countries like Canada, Australia & Russia will be fine in the long run too, tbh.
What we're witnessing is a breakdown of global supply side economics, but any country with enough landmass to produce most things it needs within its borders if need be will ride it out better than small landlocked Euro countries. Shit's going to get a lot more expensive because cheap overseas labour is drying up and there are sanctions with Russia, but you're not going to go to the grocery store in countries that produce a surplus of food like the countries I listed and not be able to buy something to eat.*
*People will point at the Soviet Union as an example of this happening in Russia, but that was because farms were collectivized and the actual farmers were shot, not because the country was not capable of producing more than enough food,
