I agree, I think the government guaranteed wage is only 100rs per day if doing roadwork or similar. (Not sure the correct term).
I believe in the Kolkata superb area, many people with a bachelors or equivalent only make $60-80 usd a month. (4000-5500rs)
Of course, there are many many many people who make much more.
If I think of what it costs to eat out in the US, and what it costs to eat out in India...
200rs is probably more equivalent $15-40 dollars in the US. For buying power.
Examples:
Throw pillow that would be $30 USD, is 150rs, or 315rs at someplace like Anokhi.
Streetfood that would be ~$10 in the us is probably around 70rs ? But that’s even a hard comparison, as I’ve been able to snack for 20rs, but not a full meal.
A knife I bought to open coconuts, that isn’t pretty, but would probably be $25-$35 in the US, was 325rs, and I probably could have gotten it cheaper.
