Help please? I just need to know how to do this, it's practice for an exam. Thanks! Consider the following exchange: I don’t know why people refuse to acknowledge this point “Our deficit hurts our economy” “No it doesn’t” “What’s the formula for GDP” “GDP =C + I + G + (X – M)” “Lowering M increases GDP. It’s math” How would you respond to the exchange above as an economist? Be specific and clear when crafting your response. Explain...
