The caste system to me means to put people in the position of a caste on purpose. Just like the younger brothers in feudal europe were second class ... so a prince might just kill his older brother. Or literally enslaving countries wholesale as untouchables (the name being an improvement over beatables, I guess). I have a hunch that caste is cognate with castrate, but it's inexplicably "uncertain" as many such terrible topics are, and indeed it's more nuanced: e.g. castrum is linked in the wiki (think casa). It makes sense via separate<enclosure<cover<layer ... it's much more complicated then that though :/
