> It's not a good sign for the US
Ideally the rest of the developing world grows far richer than they are today, which gives the US (and everybody else) more lucrative trading partners. Countries like: Vietnam, Indonesia, Brazil, Colombia, India, Nigeria. Even present mid-tier nations like Estonia, Czech, Slovakia, etc you want to see them go on to become the next Austrias and Denmarks. It's all very beneficial to the US and everybody else.
