Things that are supposed to happen
 The baby-boomer generation, which is a phrase that refers to many people who were born after World War II in 1945, will be at least 65 years old, which will result in many people retiring (stop working due to old age). Many people will think this may make the government have less money than it should due to government services retired people use, such as Medicare and Social Security.
