As long as necessity is socially dreamed, the dream becomes necessary. - Debord
I think of keeping up with the Joneses when I read this Chiasmus, we pursue goals and aim for things we deem necessary not because they are truly necessary but rather because we "collectively" dream of them to be necessary. In reality, it does not matter how insignificant they really our and how insignificant our pursuits really may be. As long as we all dream of them together, they become a necessity.
