@simon_brooke I don't think that's going to happen. China is not positioned the same way US is, nor does it have 800 military bases around the globe to force its will on others.
I think what we'll see is a multipolar world where there isn't a de facto reserve currency that allows one country to dominate others.
@simon_brooke it's also worth looking at the Soviet Union as a counter example to the idea that a larger economy has to exploit smaller ones.
USSR spent a lot of its resources helping developing countries like Cuba and Vietnam. Once USSR dissolved the conditions in these countries became worse. If USSR was extractive then the opposite would've been the case.
