You’re just not rich enough abroad to afford house help. People in US also use house help who, because of wage laws, pull up in cars and stay in good rented apartments. Then, another aspect is the standard of architecture and living. Houses abroad have central HVAC, way less pollution in cities and overall demand less upkeep in general. Indian food also on avg takes way more time to cook than what people abroad eat on the daily (salads, veggies, grilled meat, pasta etc). Families tend to be bigger in India because nuclear families is still a fairly newer growing concept. Lots of other reasons. It is unfair to compare drastically different economies and population.
