Some people in academia, despite extensive education/qualifications, seem to have a disconcerting ivory tower concept of the world. These are quite literally trust fund babies who grew up with multiple vacation homes and cannot understand that a nice car, rather than a must-have, is a rather bad investment and quite a bit down on the list of priorities. Was this candidate coming straight from undergrad to grad school and then to a PhD program? This might explain the lack of awareness of just what 'normal people' do with their money. It may also help explain the complete lack of social mores that one would have developed quickly if they had worked before.
