That is specifically about food. OP was talking about jobs in general. If you survey Indian history you can find examples of castes or individuals taking up new professions over time. Take “rulers” for instance. How many dynasties have been non-Rajput? Some of them did try to paper over their origins by retroactively claiming Kshatriya status but others did not. What I am pushing back against is the idea that there is one static monolithic hierarchical “caste system” that explains Indian society. Reality is more complex.
