Balance is already tilted towards the US both militarily and economically with US and it’s Allies in control of global financial system.
The only difference being the US no longer has overwhelming advantage in select areas. But even in those areas, DOD is trying to offset them by developing long range missiles of its own, spreading out its bases, etc…
You may be confused what "tilt" we are discussing; the tilt that is being discussed is not overall China vs the US in terms of position, but rather China vs the US on Taiwan in terms of momentum. In other words, while the US may still retain hold over several traditional tools like an overall military advantage, a Western harem, and its stewardship over the the global financial system, much of it is irrelevant when the battlefield is Taiwan, which geographically advantageous to Chinese logistics over American ones giving China a much longer lever arm to use. And while the position in those other regards is tilted towards the US in an overall conflict, they are
tilting more and more towards China momentum-wise as China exceeds the US in PPP and trade and catches up/overtakes the US by moving faster in pretty much all aspects of technology.
