What is your definition of upper caste and lower caste then?

Normally people just go with the two poles, dalits and Brahmins

And assume the priest class in Europe is analogous the Brahmin caste/Varna in india (it’s not as Brahmins are obligated to live modestly and donate excess wealth and assets)

The wealthiest varnas will likely be merchants, traders, artisans and rulers

Vasiya, shudra, Kshatriyas

But that is a huge group to generalise.

Until recently, exorbitant wealth acquisition was looked down upon and treated as a moral hazard in society as it is adharmic
