It’s probably a mix of many different views, but there’s probably a lot of Marxist leninists here. Me included.

Very few people are totally against working in general, it’s more that they’re against the current system of work/employment.

Marxism is in large a criticism of the employer employees relation. Or capitalist proletariat relation as it would be called in marxist terms. The critique is in in short terms pointing out the the fact that the workers themselves don’t own the means of production, and has to sell their labour to a capitalist, whom in turn takes the surplus value (created by the workers) for himself.

I can’t possibly write all Marxist theory on the topic here, but if it seems interesting, I would recommend reading up on it, or watching videos by well informed creators. Hakim (@yaboihakim on YouTube) is a great source of information on Marxism. And the communist manifest by Karl Marx is a very short and easily available book that has a great introduction to communism.

Hope this helps. And im happy to answer if you got more questions!
