The term "Algerian" itself would need to be defined. Camus was born in Algeria, he would have called himself Algerian, just like someone born in Corsica would call themselves Corsican.
What is certainly true is that the society (like many colonial administrations) was racist and highly stratified. the pieds-noirs (descendants of immigrants from western europe) were "below" the french expats/public servants and their families (but could get a leg up from the former, as did Camus), but "above" the arab community (who themselves would look down on the kabyle, who themselves were above the other berberes etc..)

What's the point in bringing up Camus stating he would save his mother over Algeria as something telling about his work?
When I read l'etranger I found the emptiness of the world lead me into feeling the absurdity as an emotion versus a thought experiment.
Very interesting, since English is a sort of mutant hybrid of Norse-Germanic-French. I wonder how long before a unique "Algerian" language emerges. I wonder how that compares to how long it took english to develop, i'd wager algerian will develop a lot quicker thanks to globalism/internet/etc.
In this metaphor Algerian is probably Polish or Czech in the 14th century.
