John Kenneth Galbraith said this quote

None of this excuses anyone from mastering the basic ideas and terminology of economics. The intelligent layman must expect also to encounter good economists who are difficult writers even though some of the best have been very good writers. He should know, moreover, that at least for a few great men ambiguity of expression has been a positive asset. But with these exceptions he may safely conclude that what is wholly mysterious in economics is not likely to be important.
