While it so obviously measures empathy that you could easily game it to make yourself look kinder and nicer, the fact that today's college students don't even feel compelled to do that suggests that the study is measuring something real. If young people don't even care about seeming uncaring, something is seriously wrong.
Though social media is an improvement on passive TV viewing and can sometimes aid real friendships, it is still less rich than face to face interaction. This is especially important for the youngest children whose brains are absorbing social information that will shape the way they connect for the rest of their lives.
Perhaps an even larger factor is the merging of the left's "do your own thing" individualism with the right's glorification of brutal competition and unfettered markets. You wind up with a society that teaches kids that "you're on your own" and that helping others is for suckers.
if you know nothing about someone's real situation, it's easy to caricature it as being defined by bad choices and laziness, rather than understand the constraints and limits the economy itself imposes. Seeing yourself doing so well and others doing poorly tends to bolster ideas that "you deserve your wealth," simply because guilt otherwise becomes uncomfortable, even unbearable.

It includes data from over 14,000 students.
