Society's way of pretending everyone's equal while sorting them into invisible shelves.

means The arrangement of people, groups, or things into distinct layers or ranks, usually based on status, wealth, or power.

from From Latin stratum, 'something laid down or spread out' (from sternere, 'to spread'), plus facere, 'to make.' Geologists borrowed it first for rock layers settling one atop another over time — then sociologists in the 19th-20th century saw the same quiet piling-up happening in human societies, and the word slid from bedrock to class structure without losing its sense of sediment settling into place.
