I don't think so. In the US there are more than twice as many vegans and vegetarians among black people compared to the overall public. At least that's the result of a study from 2015.

Also India and Mexico have quite a lot of vegans and vegetarians according to this source: https://worldpopulationreview.com/country-rankings/veganism-by-country

However, I do think that veganism as an ethical movement is mainly a thing in developed countries. If you are struggling to survive in a rather poor place, I guess many people don't have enough free capacities to think about animal rights.

Look up vegan lifestyle India. A lot of people already live that way just for their religion

Oh, it's THAT interview. People who have 0 (zero) understanding of sociological methods decide that they're fountains of facts because talking in front a camera automatically means you're the same as some experts or professors talking in a lecture or documentary. The video camera, the ultimate (self) validation machine, an indirect visual feedback loop acting as a circular reasoning feedback loop. It's not enough to have your head up your ass, you also have to build a TV studio in there and do vodcasts.
