I love watcher guru but I mean when you combine the two most populated countries in the world then of course you are going to have a much larger economy... Both have over 1 billion people compared to the US which has ~370 million... I mean it goes to show how advanced the US economy is.

BRICS has already started to show some cracks with China's economy not firing to well, Russia's economy is almost exclusively war based at this point, Saudi Aramco two days ago started issuing bonds denominated by USD, India's elections were a set back, among other things. Not that the US political landscape is great either but the economy is doing much better than even China and our tech is still just so advanced that it makes up for the much smaller population size.
