1. Up until 2016, the U.S. gross debt is about $ 20 trillion, larger than our annual GDP. Use Delong and Cohen's argument in the article "Where Did all Their Money Come From?" to explain how does the U.S. provide the money demand in the last few decades, especially when the domestic money demand is much larger than domestic money supply. Should we worry? Why and why not?

2. Briefly summarize Cohen and DeLong's main arguments' in the article "state-led Development". How does their key arguments relate to the government budget and trade deficit problems that U.S. are facing?

3.Use the key messages from the article titled "For the Richer, For the Poorer" to briefly explain the main causes of the current U.S. Income inequality situation.Provide and defend two possible policy suggestions to reduce the US current income inequality---what I mean "defend" is that you need to provide at least two possible counter-arguments of your own policy suggestion, then defend your own policy suggestions by using solid evidence and logical arguments. For example, if your policy suggestion is to provide cheaper education for everyone, you need to assume your opponents would challenge you with the US government budget limitation.
