This fantasy of communists that they'd all be artists and musicians and authors and it's only the 8 hours of labor a day required to survive that prevents them from creating the sublime - it's never going to die. Fundamentally this is a battle against childish delusion. Reality is the you're average and the most you can contribute is likely what you're already doing at work. Accepting your lot gives you the freedom to pursue your dreams. All of these people are spiritual slaves.
