Export-oriented economy is never sustainable, especially when it's built upon low human rights.
By many OECD economic metrics[1] around trade dependence, the US and China consistently rank as the least trade dependent. This reflects the scale of the countries, diversity of the economies, and an intentional strategy of minimizing trade dependence for GDP growth.
This last point is central to geopolitical leverage. Even if you treat the EU27 as a single trade entity, which operates at similar scales, there is little evidence of a coherent strategy to become functionally self-sufficient. A lot of geopolitical relevance is downstream of this.

The average American will keep shouting over and over again that "China can't innovate" while they quietly and slowly tick off every box on their checklist of issues. It doesn't end well for us.
