Meh its not as clear cut as you say it is.anglos trying to do 'state capitalism' are going to fail because Chinese state capitalism mobilises the entire society to achieve goals as the semiconductor industries and Huawei can testify. Anglo society can't even agree on genders, let alone scientific evolution; what chance do they have in competing against china?
Lets not forget that before Xi came in power the same things you describe the "anglos" to be where all happening on China as well. Massive corruption, massive bribes.
The CPC was probably with one foot to the grave when Hu Jintao had stepped down. And when Xi was chosen to lead China, a "soft" coup was attempted by the corrupt elements in the CPC.
The rest is history. So by saying that only China can do state capitalism with success thats only applies for the past decade. Before Xi, China was losing tremendous money for inefficiencies and corruption on its SOEs.
