Its success is due to its technological innovation, robust financial market, and ability to attract global investment. China ranks second, with a GDP close to $20 trillion, standing out for its investment in infrastructure and digitalization.
in terms of gdp, the us is better than china, but in terms of gdp ppp china is better than the us. we need to distinguish between the two, because so far people have always been based on gdp alone, without looking at gdp ppp, even though gdp ppp is also an important thing to discuss. gdp ppp is more accurate if you want to compare living standards between countries, because it takes into account the cost of living and people's purchasing power. that way we can't say one is absolutely better than the other, because even though the us has a high gdp, the cost of living there is much higher, like for now the middle class has a hard time surviving there. while in china people can still eat very well with just a few dollars.
