Frequently Asked Questions
5 questions
While China's economy grew rapidly to reach $17.9 trillion (2024), surpassing it would require China to grow at 8%+ annually for 15+ years while the US grows at 2%, which is unlikely given demographic shifts and development maturity in China. However, a unified European Union economy ($18.1 trillion combined) already approaches US size. The US maintains dominance in high-value sectors, technology, and currency strength, making displacement unlikely through 2035.
