I am assuming that one of the biggest problems is Economics Dictionaries definitions ???

in order to understand this, look at many economics dictionaries, from different authors and try to match the same words with the same definitions, I was unable to do so,

example

the word capitalism ( and many other economics words ) in each dictionary I looked at had different meanings !!!, at a colleges that teaches economics ??? and libraries that you can learn economics on your own ???

because of this, you say an economic word with in a group of people and everyone will hear the same word, but see a different meaning in there minds eye ?, which makes it difficult or impossible for people in general to effectively communicate with each other ???
