I'll get downvoted, but if I'm a father with no opportunity in rural India. This is exactly what I'd be doing. You might be a better man to allow your children starve in a pile of there own filth, but I'm not him.
I just saw an photo this week on the People of Nepal Facebook page, and it was of a man who wanted a better life for his kids so he slaved over a little tea shop in a small city/town, and was able to send his kids to school and he talks about how he can wear their expensive watches and mingle with people at parties.

"if I'm a father with no opportunity" suffices.
1) 1 USD is around 66 INR, so almost everyone is ingrained that people in USA are richer. Furthermore, the fact that stuff is perceived as "cheaper" in USA has not helped (even those who earn minimum wage in USA, can afford the latest iPhone, can't say the same about those in India).
2) Scammers can't see the damage they cause.
3) Some scammers don't even know they are scammers. (Especially the ones in IT that try to sell you anti-virus software claiming that your computer is infected).
4) personal note: I wonder what the sentence would be, if say it were US scammers, scamming Indians.
For some reason, a lot of people confuse the exchange rate with purchasing power, but these are distinct.
For example, 1 INR is 1.5 Yen, but the Japanese aren't 1.5 times as poor as the Indians (on average).
