social activity can only be improved by social engineering. what volunteering does to social activity is a pseudo-social activity that solves nothing, just like a mere empty gesture of empathy.
Volunteering is one of the most beautiful forms of social activity. It suffices to say that it is due to volunteer work that a lot people feel happier or can even survive. Per my understanding, we would be better off if those people who are in jail, were instead doing civil work.
