"Coser’s argument suggests further that bridging weak ties, since they do link different groups, are far more likely than other weak ties to connect individuals who are significantly different from one another… exactly the sort of ties that lead to complex role sets and the need for cognitive flexibility.
There is no special reason why such an argument should apply
only to lower socioeconomic groups; it should be equally persuasive for any set of people whose outlook is unusually provincial as the result of homogeneous contacts. In American society there is thus some reason for suggesting that upper-class individuals as well as lower-class people may suffer a lack of cognitive flexibility. Baltzell (1958) and others have described in detail the cloistered features of upper-class interaction; Halberstam (1972) has suggested that such a social structure
creates inflexibility in the form of arrogance and a sense of infallibility and had much to do with American involvement in the Vietnam War.
At a more mundane level, I argued that weak ties have a special role in a person’s opportunity for mobility - that there is a “structural tendency for those to whom one is only weakly tied to have better access to job information one does not already have. Acquaintances, as compared to close friends, are more prone to move in different circles than oneself. Those to whom one is closest are likely to have the greatest overlap in contact with those one already knows, so that the information to which they are privy is likely to be much the same as that which one already has”."

We are not enemies, but friends. We must not be enemies. Though passion may have strained, it must not break our bonds of affection. The mystic chords of memory will swell when again touched, as surely they will be, by the better angels of our nature.
