Don't generalize. Looks as if you have a especial hatred for fellow Indians which is coming out so evidently in your threads.
Now, let us go over your examples. Both of the areas you cited have traditionally been inhabited by not-so-well-to-do Indians which could be one of the reasons why they aren't well maintained. Little India in Singapore was originally inhabited by Indian immigrants - many of whom were very poor and uneducated and the area generally took its cue from there. Newark St in Jersey City, too, has largely been inhabited by poor early immigrant Indians (such as those who drive taxis in NYC) and Indians who come onsite (and thus are in heavy savings mode).
To give a counter to your example why don't you visit Sunnyvale and Fremont on the west coast which are heavily populated by the Indian community. Given how you have generalized, those areas should be dumps. The difference here is that the Indians who tend to live here are much more affluent and educated.
The difference here is between affluent and poor as well as educated and not. Such differences exist even within the white or black communities in the US.
You sure do rush to conclusion, do not mistake a harsh tone for hatred. So why is Hillcrest in Houston, TX not so appealing. You only want me to account Cities with average house price is about 500K+ ? Sure, while at it, why dont we not take Beverly Hills, CA as a sample to discuss crime in California. My point is, go to a place where there are a group of Indian business and you can see the contrast. If you are happy and satisfied, all the power to you.
