> Xi has shown repeatedly that he’s serious about corruption.

that's BS

cracking down on corruption has been a common tactic for decades to get rid of people who are a threat to the top dog at the CCP, and Xi has employed this perhaps better than anyone since Mao

are those people being purged corrupt? probably most are. but plenty of people who are corrupt aren't purged, it's a highly selective process.

Xi started this a few years after coming into power -- and it was obviously to the educated class was it was (I was living in Beijing at the time), but "mei banfa" (or emigrate, as many people with the $/ability to do so, did).

Xi in particular seems to be personally offended by small scale corruption like business lunches. Huge crackdown on it for probably a negative political benefit.
