Coming to the crux of the matter. Having lived in Bombay - and having had servants I can say that its in no means as "exploitative" as the author claims. Sure - an indian house helper earns less than an american does. So what? The median income in India is nowhere close to comparable to that in the US. An uneducated village boy - who would either earn a few hundred rupees (10-20 USD) a month working on someone elses farm in his village - is much better off coming to the city and earning more than five or six thousand rupees (100 - 120 $) a month in the city - with which he can also support his family back in the village who get by on subsistence farming. Many servants take on multiple jobs - earning almost double or triple of that. Which is NOT bad by any means considering he will often be provided meals and accomodation in addition to his salary. Its a simple calculation - the average IT worker earns approximately 40-5000 rupees after tax per month - assume if a couple - both employed in IT - earning around 100000 rupees per month - keep a maid to cook and clean - and pay her 10000 a month. Thats 10% of their salary - why is that exploitative? The maid is free to go take 2-3 others such jobs to fill her day and is easily making close to what the IT guys make. Until we reach a standard of literacy and education where everyone can make tonnes of money - this will continue - and its NOT a bad thing. A lot of families try to break the cycle by paying the school fees for their servants children or buying them the yearly textbooks etc - we did that growing up. At the end of the day - its a free market and these are not indentured slaves - if they find better paying work elsewhere (and often they do - cleaning malls and the like) - they go do that - and no one can stop them.
As for why people "need" servants - well - its a part of the culture and has a lot to do with economics as well. Right now - in a city like Bombay -its cheaper to have a servant who washes your clothes and cleans your house - than it is to have a washing machine (if you're lucky enough to have the space to fit one in) & a vaccuum cleaner. Its a dusty country - and you do need to clean more often than you do in the temperate regions. In families where all adults are working - it just makes sense to have a servant. Its economics and logic - not exploitation.
