Edited to add - To be clear for anyone, it's Oligarchs/Billionaires paired with rampant, unfettered corporate greed. (at least in my view)
Someone reminded me that I was using dogwhistle parlance in my use of they which may have suggested otherwise.
Here are some visual aids to accompany my clarification:
Theoretically China is what they call "communism with Chinese characteristics". Many Marxist still regard China as socialist, generally it's only libtards that have this opinion. For instance the real estate bubble in China would have been catastrophic for any Western democratic government. In China they just nationalized the company is that we're failing and forgave all their debt. Now they don't have to worry about those companies again since they were nationalized. Point to an example of a capitalist country that nationalized industry like this.
Cuba is definitely a socialist state and has not returned to capitalism. If they had returned to capitalism the us would have lifted sanctions because the Cuban bourgeoisie would be able to return and try to reclaim "their lost wealth". They consistently hold referendums for the public to vote on how to organize the National Industry. In fact they're probably the closest thing to a successful socialist project in the western world. Down to and including having democratically elected leaders that can be recalled.
Last I checked that's not something that happens in the western world. Few countries have nationalized resources and practically none of them allow people to vote on how those nationalized resources are used.
