>his family controls billions of dollars of assets
None sequitur / who cares? Xi personally doesn't have obscene wealth/assets according to relevant evidence which is what matters.
Many CCP red family nepo babies/princelings influence peddled their way to wealth in last 50 years, they get are first dibs aristocracy class and their wealth should logically snowball with PRC moving from billion to trillion $ economy.
But Xi himself specifically has been outlier in how squeaky clean, even by western investigations. Nothing has been tied to him, hence lame "but his family manages his wealth" cope. Like the bro married Chinese 80s Taylor Swift and all signs point to him being fine what he has, which is not nothing, but also not extravagant, which makes trying to associate him to stupendous graft levels corruption he is trying to fix impossible.
Of course broader PRC leadership class has lots of corruption from development, it should be expected that Xi's sister/husband, both from red families to be wealthy from PRC development, but timeline of Xi's sister/husband wealth predates Xi - i.e. early real estate / rare earth investments. Difference between Xi and Trump is Xi himself has been historically clean, and in office made his family divest/liquidate 100ms in assets vs Trump is is historically unclean and family uses his influence to accumulate.
So no, all signs point to Xi is clean as a whistle while Trump isn't, and its ridiculous to equate the two just because both families are wealthy.
And to circle to original claim, there is no evidence that Xi is fantastically corrupt, only evidence to the contrary, that he is outlier in how uniquely uncorrupt he is relative to elite prestige, access, opportunities.
