Actually, (aside from the Buddhist reference ... a Vedic one might work better here) the caste system is a good example of misappropriating a system to suit a culture.
The original concept of 'Varnas' (occupations / guilds / systems of initiation) came from Aryan culture and the pre-Zoroastrian religion. It (the original idea of Vara - or Vana in Hindu tradition - ' a farmed enclosure' ) translated into Zoroastrianism in its more original form.
King Jamshid is said to have developed it. He instituted the four main professional guilds of priests and learned (athravan), nobles and warriors (rathestaran), farmers (vasteryosan), and artisans (hutokhshan), with members of each profession working in freedom and dignity. Farmers had their own land free from dispute. King Jamshid also instituted the tradition of the wearing the sacred thread or belt as an mark that the wearer had been initiated into the guilds. It was equally open to men and women and not restricted by birth.
King Jamshid's realm was known for its fairness in government and opportunities - a first of its kind back then. This is reflected in the 'Vedic' 'old gods' ; the Asuras, who were beneficial and just (in the earliest Vedas ) .
Later, after the rise of the warlike and oppressive Indra (and after the split into proto-Iranians and Vedic 'Indians' and the crossing of them into India from the Arian homeland; Aria, then Bactria , now Afghanistan / Tajikistan) the system became set by birth, they had the priests and learned (brahman), nobles and warriors (khshtriya), merchants and farmers (vaishyas), labourers and artisans (sudra). Each varna has its own dharma or system and rules (also called laws) which included an initiation ceremony called the upanayana (meaning bringing within).
Hinduism developed the professional guilds into a caste system, a development that violated principles that Zarathushtra would promote. The initiation ceremony in Hinduism is now limited to men of the first three castes, while the initiation ceremony in Zoroastrianism is available to all women and men.

In Zoroastrianism, the initiation ceremony is an initiation into the faith and a coming-of-age ceremony for all Zoroastrians - rather than an initiation into a guild or caste for men only.
The system was clearly part of a liberal culture that allowed flexibility and development and offered a previously unheard of liberality. That part of the culture was taken and used in a more oppressive regime to suit the ends of those that sort personal power and more control of the populace.
In the Rig Veda, the devas (Hindu gods) preside over natural phenomena and the exercise of power and might while the asuras (Zoroastrian 'gods') preside over the establishment of a moral and social order.
In the Rig Veda , when Varuna ( an asura) declares, "I, Varuna, am the king; first for me were appointed the dignities of asura, the Lord. I let the dripping waters rise up, and through rta I uphold the sky."
Indra replies, "Men who ride swiftly, having good horses, call on me when surrounded in battle. I, the bountiful Indra, provoke strife. I whirl up the dust, my strength is overwhelming... . No godlike power can check me - I who am unassailable. When draughts of Soma*, when songs have made me frenzied, then both the unbounded regions are filled with fear."
* Soma although 'lost' to the migrated 'Indians' can still be purchased as a draught in Tajikistan markets , it is made form a herbal ephedera - ie. 'speed'
Indra is guardian of victory in battle earning the title sahasra-mushka, 'the one with a thousand testicles' ( - talk about a testosterone overloaded, violent, speed freak !
)
~ In case the point is missed, the cultural system (Vana) was developed to help a culture be free and advanced, the system was misappropriated for oppression and control.
- another type of cultural misappropriation.
