IMO China has a better history since 1980 of implementing
policy to rectify structural economic problems that that of the USA
To assume that China is similar to the then USSR and that its
fate is similar is a mistake because both Deng and Xi have
structured China's economy to avoid the Soviet weaknesses.
If the US vs China were to be a Super Yacht race, then the US
us skulking behind SuperYacht China trying to take the wind
out of its sails rather than getting out there and going for it!

It is always IMHO a mistake to compare with another rather than looking at the virtues of the individual
The USA problems are IMHO 70% due to the current leadership and I would say that if Harris wins the next election it will mark the end of the USA as a major country within 6 years and china will come to the fore
China has it's own problems which IMHO will increase in line with it's economic growth and will also eventually within 40/50 years flounder and die
Politicians of all sorts always try and blame others for their own problems but in fact as in a business, you have a plan but you have to be flexible enough and adaptable to alter so as to take into account the changing scenerios
It is a fact the political parties never win, they are always successful due to the faults of the loosing party, or they have a monopoly
The USA have made themselves weak by encouraging uncontrolled migration ( the majority are Chinese fit young men) with the resultant degradation and crime that will occur with uncontrolled anything and IF Trump survives to be elected he will have to be able to have a massive eviction program to enable the USA to rebuild, if that process takes too long the USA will fail
Time will tell
