Most nations had inflation -- so "devalued" is not in relation to other currencies but in what the monetary unit can purchase.

I dont really need to, because it was clearly obvious during the pandemic response of the massive inflation that occurred, but the dollar is the base currency of the world outside of China/Russia's sphere. As you observed, the Euro is pegged to the dollar right now.

How has assets done compared to the Euro? How has house prices? Housing, land, stock indexes, and even consumables like tools, groceries are all doubled their 2021 prices.
