College students 40% less empathetic than in 1970's

>>>Compared with college kids of the late 1970s, the study says, today's are less likely to agree with statements including "I sometimes try to understand my friends better by imagining how things look from their perspective" and "I often have tender, concerned feelings for people less fortunate than me."

None of the reasons in the articles included the fact that students have debts of five to six figures by the time they complete their degree(s) in their twenties, versus zero in the 1970's, meaning that the biggest reason could be that students feel there are fewer people worse off than they are. Also, with more students in college than ever, there is likely a greater percent of students from working class or subsidized-living backgrounds, again feeling less empathy for the few people who are less fortunate, as many of these are already in college like they are.

who cares?
