The Fed has the dollar, the Russians have the rouble. Just print the latter without end and you get Weimar levels of inflation. Also, they might have oil and food but they don’t have the technology to build the stuff.
The Fed printed $4 trillion and here we are. American Weimar?
As for tech, you can live without iPhones. Not without food.
Oh, and as for poor tech, ask the ISS crew how they got there and how they will get home.
