The dollar will remain in place as long as the US Army is the defacto world government's army.
That may not last. I don't think China was expected to have recovered this fast. The takedown was only a knockdown so far. If they come on strong and can manage to play nice with Russia, then the US is in for a big struggle.
Iran has faster and better missiles. Ditto Russia and China. A concerted push on 3 fronts? Then what? Instead of a $3 trillion nationAL DEFICIT MAYBE WE COULD GO FOR A $4 TRILLION DEFICIT?
I remember when a $250 billion dollar deficit was big news.
They will create money in whatever quantities they can get away with. Wall Street gets the first cut, then the federal government, then smart or lucky investors, then the people might get a job or see their house go up in value. That is, until they decide to stop creating money to "save the dollar", then Wall Street makes money selling short, the government "slashes" the budget, and the people lose their jobs, businesses, and homes.
