Final answer:
Jessica's job as a computer systems analyst after her parents' bookkeeping jobs represents the shift in job markets influenced by automation and technology, leading to higher pay for skilled positions.
Step-by-step explanation:
Jessica's transition from the occupation of her bookkeeper parents to her job as a computer systems analyst is an example of structural changes in the job market due to automation of the workplace and technological advancements. As computer spreadsheets replaced the need for traditional bookkeepers, new opportunities have arisen in areas such as computer systems analysis, which tend to offer better compensation and higher status. This shift reflects a broader move from labor-intensive jobs to those requiring higher levels of education and specialized skills, often leading to increased wage inequality between high-skill and low-skill workers, as well as changes due to outsourcing and job consolidation within companies and industries.
