Oscar Wilde was responsible for the original form of the quote but I am not sure where I heard the following one... nonetheless I love it.
“Economists know the price of things but not the value and Marketers know the value of things but not the price”.
I recently told someone they knew the value of things but not the value of it and they lashed out at me. I had particularly chosen not to generalize the Economists and the Marketers when I said it out loud. The quote is deep and indicative of the equity the two functions have developed as cynics and romantics.
