The decorations on Tazias

So i remember in a village divided, in one strip (I forgot if it was the northern or southern strip), the tazias are decorated by the high ranking members of the village only while in the other strip they are lower caste members are given that honor. It turns out, the professor explained that it is not really because of social tolerance and fluidity that they allow the low caste members to beautify the shrines, rather, in that particular part, people with status consider the job beneath them and therefore assign the duty to the bottom caste. Interesting.
