Why is Jwala Gutta angry?

"If a singles player gets 10 dollars and a doubles player gets two dollars, that in itself would be great, but in India we get nothing. We had won a very important match for India and we came back to an empty airport. The singles player, who hadn't come as close as we did, was greeted with so much cheering at the airport," said the 30-year-old, who won a bronze medal at the 2011 world championships.
