Star trek doesn't really have a working class though, they achieved Marx's earlier hypothesised state of the deprecation of manual labor (in the technical sense). Interestingly, most of the philosophy is around how to get to Star Trek, where Star Trek itself is kind of the biggest thought experiment we have for what we would do once we're there.

Marx later evolved to believe only a revolution would destroy capitalism, and that's what Mao focused on, the getting there. Through violence.

Mao took that to heart, and succeeded, despite his best efforts, in ultimately setting the stage for a China that's more capitalist than it's ever been.

That's kind of the magic of star trek. Theres a violent past, a billion deaths, and it isn't a new political system or a different economy that changes everything, it was a newfound hope that things could be better if people were better, and they worked together to make that happen.

I think younger Marx would have loved Star Trek. I'm not sure about older Marx or Mao.
