" Paradigm " is a word that refers to the grand unifying ideas that underpin our understanding of a phenomenon - perhaps all phenomena. Paradigms shift slowly as the old "believers" die and a new generation is open to new ways of thinking. "Understanding" in this case is mostly about language: about how we talk to each other. If two people  subscribe to the same paradigm what they say to each other is intelligible - it "makes sense". Challenges to the paradigm always come in the form of impertinent questions.

We also have times, such as the "Dirty 30's" where, for technical reasons, nobody had "money" but everybody had more than they need of some things...
