Yup, only the "lower" quality Indians seem to be in Singapore. Half of my colleague in my department are originally from India and yet I don't see any issue with them. One of them even moved back from UK because he can't stand the weather in London.
There are 3 countries that fall in this boat - India, Philippines and China. The bubble burst around 2000 when qualifications and quality of work was found to be suspect. It has been a painful lesson for the world to learn that cheap is not after all good. US employers began canceling their work visas of these chaps based on cancellation of projects / workload rather than the contentious grounds of performance.
These same people began surfacing from 2003 in Singapore and getting employed because of their US employment and Singapore liberal stand on FTs. Because of their parochial habits, friends and relatives are also brought in. Really a sad story.
