Unit 4 The tipping point

Hello, I think that this unit talks about things that people do every time and why they do this. Some events that happend around our lives. The people are cosumed their times on the mall, supermarket, and others places where we can bay many things. In my opinion , one of the problems is that people dont take  control of their money and they are out of control in this part. The tipping points means an important moment . In our country , Dominican Republic , that happened some important moment , for example , Trujillo's dead. The country was prisioner of Trujillo and his men . After that, Dominican Republic was free.
