You draw a dollar sign - does it represent a cash, money, capitalism, wealth? Players are guessing all of these, and it is critical that they understand that you are drawing 'money' as your word is 'money man'.

I propose that you point (with an arrow) to the player who guessed the right idea, so players know on what track to continue guessing. If the player said multiple things after you last finished drawing, draw a number next to the arrow - so if Bob guessed money and cash, draw an arrow by bob and a '1'.
