It could affect the health of someone by them not being able to afford health care. Say they dropped out of high school and the only job they could get was working at mcdonald's. They don’t have enough money to afford health care because they have to pay for food and pay there bills.
They would be a danger to society because of the drop employment rates. It is getting harder and harder to get a job more or less a good job. Without a High school diploma this shortens the chance to get a job by a-lot.The more kids who either drop out or fall behind reflect on the school. Because of this the state would give the school less money in turn making it harder to get good teachers. One way to help this is to have tutoring classes and after school help.
