“For the poor always ye have with you…” Luke 4:18
“For the poor shall never cease out of the land…” Deuteronomy 15:11
Everywhere in the world there is class: people dividing themselves into lower and higher and dividing the output of society unevenly. Further, in every subunit of a society or culture, whether in a church, corporation, or neighborhood association, one likewise finds rank, class, and caste. There are cliques in every school, and every group knows where it stands on the social scale.
Race, as right-minded people know, is an illusion. Certainly, genetic content can vary by group (whether these are perceived as “racial” groups or not), but ultimately we are the same species and vary as much between two individuals in the same race as between two in different races. Further, race is a constantly shifting thing, as people from different groups interbreed.
But the superficial differences perceived as “racial” are just what the dark side of human nature and human cognition desire as marks by which to determine class and caste. The inferiority of people with readily identified characteristics was extremely useful to enslavers and conquerors. Their economic incentive for doing so was great.
And so it is today. Caste and class are alive and well in the United States, and those in power seek to support those they identify as being like them (“one of us”) and preserve the prerogatives of their group. Race is but one factor in this system: Family name, ethnicity, religion, schools attended, etc. All may serve as shibboleths.
I think this desire to descriminate on the basis of non-essential characteristics is at the heart of racism, and the notion that people of one color dislike or discriminate against those of another ought to be identified as just one subset of the human tendency to keep outsiders out and insiders in.
In other words, it’s nothing personal: it’s the same old self-serving injustice that has always been with us, and always will be.
