everyone lies about everything here. the big question will be if china can build up BRICs into a worthwhile economic alliance for them. if they can keep Russia's resources and india's manpower while keeping most of the 3rd world neutral they got a shot. they will probably shot themselves in the dick trying to keep it together though. we on the other hand got our own issues to sort through that I honestly think will plague us for most of the decade. NATO sticking with us when we can't be their sugar daddy is not a bet I would take. thus my thought that I don't really know and we are varying levels of fucked and it depends on how well we can land this shit compared to china who I can't make an assessment of because too many people lie about. both pro and anti china sides mind you.
China is fundamentally incapable of an 'economic victory' in a duel for global dominance. Before Xi came into power, and there was still a general (but very fragile) trend towards more and more economic freedom, it might have been possible, but as they've gone more and more into it, they've doomed their already-fragile system to a collapse.
And that's going to take most of their untested military capacity with it.
