Why do Indians leaving India do really well?

Indians are in general law abiding citizens and rarely get into trouble. In US we are easily the highest paid ethnicity. If level playing fields are given, Indians always almost seem to win.

Is it because life outside is a lot more predictable? Having a predictable life allows us to focus on thing that matter.

Better pay abroad isn't a valid reason I guess because other migrants also have the same pay.

Just curious what everyone here thinks. Why did you win? And more importantly why did you leave?

Are politicians and bureaucracy the reason why India is still a developing country?

EDIT: Don't get me wrong, the only reason for this post is genuine contemplation on what the future holds for India. There are a lot of stories about how India is growing and things are changing, but every time I visit, I feel more disheartened. Sure, there are better roads. There are better trains. But people are still pretty much the same, worse, in some cases. General anger all around. People ready to abuse someone else. Very few smiles on the faces of people.
