True! Thankfully under Socialism there wouldn't be a Grand Prix in the first place, and the Hotel would be government-run and only house Party members during special events anyway.
I think you might be under informed... this is how authoritarian communism has worked, historically. But Socialism covers a massive umbrella of different ideas beyond just authcom ideas. Social democracy, democratic socialism, anarchism, syndicalism, authoritarian single party rule, council communism, etc etc.
Socialism also isn't the only system that isn't capitalism either. Capitalism is a relatively recent invention, perhaps 300 years old.
