Why do Indians hate NRI?

I read this article in Indian express. I cannot comment on the credibility of the stated persons as I have no clue who there are. But I can definitely comment as an NRI (presently) who had visited India few months back. First of all just because I critize does not mean I hate Indians or India, or there is nothing good back there. Yes, the roads are bad, too much pollution, too much corruption and so on. But I am not criticizing India for all these. I have been brought up in a proper middle class family in chennai, so that Nobody should assume I dont know anything of the poverty that exists in India (not my family, but I have seen). What irritates me the most is the lack of ethics in India. We consider ourselves to be superior culturally to the west...or are we really superior? Having seen both the cultures, I feel on a common man's regular life west seems to have better ethics that us. I have not seen people waiting patiently in queue, saying thank you, smiling at a hotel server when he serves, helping old and pregnent women, giving preference to children etc. These may be small things, but I think it is absolutely necessary that if we want to consider ourselves superior we need to inculcate these habits in us. Cleanliness, awareness and interest in environment, truthfullness and honesty etc are some i think which we lack. We have to understand that we are responsible for the world we live in and not just out homes. Important things like voting, altert citizens in the community, fighting for rights.....I have seen so many Indians not caring about these. And lastly complaing Indians. I hate them the most. People who can come up, who can make a difference simply complain at the lack of things that they dont have. Everyday morning when I go to jog at 6.30AM, all I see is useless bums sitting on roadside tea-shops talking about things that are abolutely nonsense. In the time they waste there, they can help their wives, get the children ready for school or something, go to work ...etc. Are they not allowed free time.....NO. Absolutely NO. These people are poor. They need to come up in life, give their children a better chance to live in the world...If I were there in their position, I will be working my ass out. I mean it.
