behavior modification

this poster is based on chapter 4 of the secrets of the temple book. i took a quote about interest rates and put that inside the arrow. the idea is that by increasing/decreasing interest rates, the fed can affect the behavior of consumers and businesses in a way to get the outcome they want. 

i know there's a lot of information here to read, but i don't really know how to communicate my subject in a simpler way other than using language. i hope i'm heading the right direction with this one. you guys tell me...
