@yogthos The dollar being the world's principal trading currency has effectively allowed the US to extract rent out of everyone who traded commodities round the world, because they had to hold dollars in order to do so.
Of course, that rent-seeking opportunity is not disappearing, it's just switching to China. Big economic powers will always systematically benefit from market economies at the expense of the poor.
@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.
