Dollar economy isn’t going away, but the world economy will become increasingly bifurcated going forward. My point wasn’t that the dollar was going to disappear, but rather that dollar based economy is already shrinking. One of the main reasons dollar was in constant demand was that you had to buy energy in dollars. Every country needs oil and gas to operate, and since the dollar was the only currency you could get them with that made dollar as good as gold. Now that Russia started trading energy outside the dollar this is no longer the case, and we’re seeing Saudis follow suit which is a complete disaster for US.
