Isn’t claiming to be a Marxist state while still maintaining power within a small group of people (the inner party, a political version of the bourgeois) worse?
The Chinese system isn’t perfect but I think questions like these put the cart before the horse. Is the Chinese system set up in such a way that, if bad actors got their way to the top, they would wield an immense amount of power? Yes, definitely. This question is separate from whether or not the people at the top right now are bad actors. And I think, like in any country, it’s a mixed bag; there are oligarchs and business-industry plants and corrupt officials, but there’s also well-meaning bureaucrats (Xi Jinping broadly fits into this category) and ideologically-driven Marxists.
The idea that Xi Jinping is a power-hungry dictator is an overblown trope. He is a fat, old, boring bureaucrat who got into office because he is an agreeable political moderate; a compromise between the ideological Marxist wing of the party and the pro-business Dengist wing.
As we saw in the Soviet Union, unrestricted Freedom of Speech is the downfall of Marxism. Home-grown Liberals are only the first issue; the United States government spends literally billions of dollars propping up anti-government organizations, whether that’s Uyghur terrorist groups, the Falun Gong, Tibetan Independence movements, or “LGBTQ+ Rights” organizations who always seem to spend more time arguing for political liberalization than they do actual LGBTQ+ Rights (and, before you strawman me, I want to make my point here clear: LGBTQ+ Rights are good, but many such organizations in China are funded by foreign actors in order to disrupt Chinese politics. The bad things about them are not their LGBTQ+ Rights advocacy, but their advocacy for other forms of Liberalization that undermine Communism in China. If an LGBTQ+ Rights organization in China calls for the downfall of the CPC, they do not deserve to exist)
