Socialism has loads of variations. Communism is proven to not be working. Whenever someone wants a more socialist society, it doesn't mean they want communism. Even Hitler wanted a socialist society, the word 'nazi' comes from national socialist. Socialism is good for society, it's just bad for rich assholes who love to exploit others for their own wallet and power. This is clearly visible with the way Elon tries to convince others: he can only use dumb memes as he clearly hasn't got a single solid argument to prove his point.
