Carla, a college junior, is participating in a special "elementary education outreach" project in her local community. Along with other students from the business school, she is going to spend the day with fourth and fifth-grade students and introduce them to the opportunities of going to college. One of her tasks is to lead a class discussion of the questions: "How is the world of work changing today?" Help Carla out by creating an outline of the major points she should discuss with the students.
