That's the biggest problem with socialism... Everyone must "participate" otherwise it won't work. And those who don't want to participate will be made to do so. That's where the totalitarianism comes in.
Usually the only way to get 100% participation is through the brutal subjugation of those who don't want to participate. Or, in the case of a "democratic socialist" state, the majority simply votes to take the stuff of the minority.
