Oh Lord God - let them build their stupid wall.
In less than 20 years, they will regret it.
The gross national product of the US is questionable on the whole because it is generated from questionable stock market transactions.
Due to the currency exemption from gold as a security guarantor, the US generates only fictional bubbles.
In the near future, when China and its allies suddenly return their currency to gold, the dollar is not worth a penny.
In this context, I would advise Canada to build a similar wall.
Real - USA you are so broken.
