While it is always good for executives to learn how long-established and well-run things work, it looks to me a lot in this system depends on the social context of Mumbai (or other big cities in India): big income disparity and the prevalence of stay at home domestic partners. I mean the first example in the article is a stock broker who has food delivered from home, cooked by their spouse. Why would this work in countries with a set minimum wage, double income households, and restaurants that have to be able to maintain their margins after delivery fees (something that domestic partners do not have to do)?
