This is the beauty of true, individualistic socialism: That the needs of family members are addressed by family members. This arrangement requires that each person giving does so of their own volition. It also requires that the person receiving does so with gratitude and appreciation. In other words, the socialism of the functional family relies on individual agreement to participate within it. If a caregiver is coerced into giving or if a recipient comes to believe that they have earned the right to receive then the whole thing falls apart. No longer will the giver provide the best that is possible. No longer will the recipient be satisfied. If there is external pressure given to maintain the socialism of a dysfunctional family, then it becomes collectivistic socialism.
Individualism respects the rights and responsibilities of the individual. It requires an understanding of personal property and privacy. Individualistic religions expect the person to make their own decisions about their beliefs and respects the dissent of people who choose not to believe as the majority do. Individual socialism allows the individual to establish their own relationships of giving and receiving so that there remains personal responsibilities between the participants. Individual Capitalism allows people to trade freely, ability/asset for ability/asset, without coercion from external forces.
Collectivism denies the individual privacy or personal property. Collectivism compels compliance with societal rules such that people of privilege or power can determine which rules apply to the masses and which apply to the elite. Collectivistic religions demand that populations adopt their beliefs uniformly and without individual variation - to the point that resistance to submit ultimately ends in the death of the non-believer. Collective socialism strips individual preferences and desires from all but the elite and spreads misery equally among the masses. Collectivistic Capitalism limits the items that can be traded, establishes standard values for the trades, and intrudes external oversight and taxation into the trades between individuals.
All philosophies of religion and political organization can be segmented into individualistic or collectivistic versions. Libertarianism generally leans toward individualistic perspectives - that the individual should be free to determine their own morality and path in life. If the right to privacy and personal property are maintained then it is understood that personal choices should be curtailed when they infringe on the choices of other people. Communism generally leans toward collectivistic perspectives - that there is no individual privacy or property - that all people are in essence the property of the state.
In simple terms, Individualism = Freedom & Self-determination; Collectivism = Slavery & Limitations. So when we freely choose to engage in giving our assets and/or talents to others we choose individualistic socialism. When private property is confiscated or externally allocated then collectivism has overtaken individual liberty and freedom.
