The setup is a false premise. It wasn't just the Nazis doing that. There was no clean line separation where only the Nazis were involved in the Jewish Holocaust. Historically such isolation of actors never really exists. Germany didn't kill six million Jews without the help of a large number of of non-Nazi Germans (their role in enabling the Nazis to power and conquest, supplying the Nazis, and in some cases direct assistance in the genocide; it was not uncommon for Germans to intentionally look the other way at what was going on, it was an open secret).
Presently China is the CCP, the CCP is China. They're inseparable as China is a one party dictatorship, and not subtly so. The CCP rules China top to bottom, in all aspects of culture and economy, without exception and without challenge. Their power is absolute over the nation. That said, I'm not implying it's reasonable to compare the current CCP China to Nazi Germany either.
Absolutist much? Have you ever even visited China? (I look forward to the response "Why would I visit such an evil dictatorship?".) A lot of the population of China are also just trying to get by.
I don't know if these scammers are independents, CCP members, sanctioned by CCP, or "rogue" members who would be punished if the higher-ups think the whole thing would make the country/the party look bad.
IMO the absolutism in your last paragraph is also how Al Qaeda justifies smashing planes into towers, equaling the controlling elite (and their actions in foreign countries) with the population, and saying "Killing the population is fair game.".
