Except it's not "they didn't have anyone to discriminate against - so they invented a group", it was class based to keep people in those jobs be excluded from almost everything else and exploit their labor that way.
Yup, legit just a group that did the jobs everyone considered "unclean" but was also vital for society (i.e. butchers, tanners, trash collectors, etc). Blood based class systems are legit just old timey artificial racism (i.e. creating outgroups)
The existence of the Burakumin proves to me that in the absence of an out-group to discriminate against, a people will artificially create one
