As I've argued elsewhere, while most of us are unaware that we've been taught (and are taught, and are teaching) this lesson, just about everyone alive today has been raised to believe that the weight of someone's needs may depend on how we value them. By the time we're adults, this idea and logic are deeply rooted, though though people differ in how broadly they apply it. Sadly, most of us apply this logic to our thinking about non-nationals, and people with a different ethnic background. Elites think this way about non-elites (esp. the unemployed, the indigent and the "less educated"). Most of us tend to victim-blame. And so on.
