The term that refers to the discrepancy in income between Suzanne and her grandfather despite her higher education is "income gap". This describes the difference in income between different individuals or groups, often based on factors such as education, age, and occupation. "Income disparity" is a similar term but can refer to broader differences in income across a society as a whole, while "education gapping" and "systemic ageism" are not relevant to this specific scenario.
