I may be naïve but I really struggle to understand why anyone would advocate for an authoritarian system, regardless of flavour.
Capitalism is definitely far from perfect. It seems to me to work best when it incorporates certain socialist elements(?), like nationalised healthcare. I feel like UBI could be the solution to a lot of problems with the system. As for my own country (UK), things have got worse since the privatisation/neoliberal policies of the 80s and whilst it feels like we have a good system in principle, it's currently being rowed by a conservative government who aren't putting the necessary funding back into the services to keep them viable. And then people point to those services, saying that the NHS is a failure (by no fault of it's own). I don't understand why we're not taxing the rich more.
Anyway those are just my feelings. No system is perfect, but I don't see why anyone would strive to become like China.
