I've seen this attitude among wealthy Indian families in India: it's culturally expected to try and pay as little as possible for help (and everything else for that matter). This same kind of thing has happened in the US with wealthy Indian families there (I think one was even the Indian consul general or something).
I didn't grow up like that at all, so I tend to discreetly slip underpaid people cash when I'm in India, even if I'm way less wealthy than their employers. It hurts to see people treated like that, especially when it's your OWN PEOPLE. I think it's tied to the caste system, but I'm not an expert by any means.
I was at a fancy private gym in Mumbai several years ago. There was a rule on outdoor shoes inside the gym. The security guard was a nice guy and since I couldn't find shoes my size over there, he told me to take my outdoor shoes off, walk in in my socks. and then put them on like they were indoor-only shoes.
The night I was leaving, I was looking for him. He was asleep on the concrete floor in the stairwell. No mat, no cardboard, nothing. Just laid out asleep under the harsh fluorescent lighting. I put a large amount of money in his shirt pocket, but figured I'd better wake him up before someone took it from him. He was very grateful but looked utterly exhausted.
It's common for help to come work in the cities from the rural areas and they never get a day off. They go home when they can (once every few years maybe). Until then, they work every day for very little money. They often have large families to support and significant debts.
EDIT: yep I remembered correctly.
