>>given that the alternative would be spending 12 hours sewing fast ...
That is the best case scenario. Mostly women roll beedis(a kind of needle sized cigar) on which you get like 1 paise per 10 rolls or something like that. Or worse do assorted labor chores which can really sap one's soul real fast.
Even with all that women actually have it a lot better than men. Men literally die and are reborn every day in most parts of India.
Just drive 30 kms North of Bangalore, and you will see abject poverty scenes. People scavenging bovine dung for fuel, children with flies, no clothing. The ever present scene is always that of an elderly person with pencil thin legs wearing shorts he likely is wearing since a decade with nothing but boiled rice and salt water+turmeric to eat daily. 8 - 10 hr power cuts are the norm, that is if you can afford electricity at all. Most health care is either entirely absent, or you have to travel to the nearest metro and hope you don't die out of hunger getting treatment there. I could go on but that is life here.
£260 a month is actually great for some place like this.
