Answer:
Two countries make more goods than their people can use.
Step-by-step explanation:
Say that a tissue box company just made 2,000,000 tissues today, but each day only 1,500,769 are being sold. Their country is in dire need of dish soap.
Say a dish soap company in another country made 1,500,000 bottles yesterday, and the country is in need of tissues.
What's left to do but trade some tissue shipments for dish soap?
