So the failing with pure Marxism is the assumption that the individual producers will feel "devoted to the cause," so to speak. I think it's hard for people to feel motivated for long based on altruism or ideology.

For example, very few people I knew while serving in the Air Force were super-patriots. There was some feeling of serving the common good, of course, but the higher motivations and more common motivations were job security, income, and career advancement.
