Each source discusses individual interests within a collective community or society: 1. Source I supports a welfare state that allows individuals to freely pursue happiness through community support of basic needs. 2. Source II argues a socialist community fails to recognize individual economic interests and responsibilities which are needed for local and global sustainability. 3. Source III depicts wealthy men who feel an economic boom should only benefit their interests, not those of poorer individuals, showing a conflict between individual and collective interests within a society. The sources relate in their discussion of balancing individual interests and the interests of the collective community, but differ in their views on how individual interests should be supported or prioritized within the collective.
