I don't think that's true. Yes, the Trump admin is horribly corrupt, but a collection of states just won in court, finding that Ticketmaster was an illegal monopoly. There's a chance that after Trump goes away / dies that whoever replaces him will take monopoly enforcement seriously. It's a popular bipartisan issue.

Meanwhile, in China, what President Xi wants, he gets. At the moment he doesn't seem to be doing the Trump speed run of corruption and personal enrichment. But, rule of law in China is limited because ultimately it's whatever Xi decides.

Privacy is basically non-existent in China. Sure, the US tries to spy on its citizens, but often the FBI is reduced to buying data on Americans from private companies because they can't spy on people directly. There's a lot of self-censorship in the US, and oligarchs are buying up media to restrict what views are published. But, that pales in comparison to the Great Firewall of China, and the massive internal censorship network.

And, keep in mind, that's what China does to Chinese citizens. When they show up in Africa they definitely don't treat Africans the same way Chinese people are treated. They are happy to help Chinese companies do corrupt deals that would never be permitted in China, but when it's Africans that suffer they really don't care. The US was hardly an angel around the world, but at least it made tiny steps towards trying to curb things a bit, like the Foreign Corrupt Practices Act.

Trump may be speed-running overt corruption and self dealing, but there are still remnants of the old system of laws and rules that occasionally stop some of the things he's doing. Xi is not as obviously overtly corrupt, but the Chinese system has never been in any way democratic. It has always been one where the people at the top get to dictate how the people at the bottom live their lives. Personally, I'd prefer a fighting chance against a corrupt mob boss style dictator who hasn't yet fully corrupted the entire system, vs. being ground under the boot heel of a "president for life" who maybe was making decisions that he thought was best for his country, but who isn't even willing to allow protests or mockery, let alone the free communication of ideas.
