This is one of the core complaints atheists and agnostics generally harbor towards organized religion in general.

Religion or no, social stratification is kind of baked into our societies. Its not something that's isolated to one period of time, one section of geography, or language, or belief system, or economic or legal system. There's nothing wrong with that, as long as the systems are fair. But figuring out what is "fair," and who gets to decide and enforce those concepts of fairness is where we've struggled as societies throughout history and will probably continue to do so. In defense of religion, there's tons of writings that embrace fairness, social stratification or no, from concepts like what makes a just ruler, to generosity and hospitality, to honesty and humility, to adherence to concrete laws and concepts of justice. But religion is often like a Rorschach test in a way, where what we choose to focus on as individuals and societies is often just as much as a reflection of us as it is a reflection of the religion.

I think right now, we're very much in a time where we're reflecting on that concept of fairness in regards to modern society. Whether we're looking at wage inequality, automation, disparities in wealth, the impacts of economies on societies and the planet, we're in times of great change and uncertainty. Things are changing very rapidly and with a lot of uncertainty. I think articles like this will keep popping up in the coming years, as more and more people really start to think about these ideas, to varying degrees of depth and success. A lot of them will be from Millenials and Gen Z, because while these things aren't new, they're new to them.
