You, make a great point. In my very personal experience and observation, the Indo American Ethnic group are the HARD WORKERS, they don´t mind picking fruit, doing hot work on a roof, and most American employers are delighted to have someone who will go the extra mile, and smile, and get to work on time. Many of the Ladino or Spanish speaking people tend to be more laid back about work, wanting to quite work early to go drink beer.
I don't doubt your observations, not having had any exposure to Indo-Americans as a group. But I have a question. If that's the case, why aren't their governments more successful at providing for their nations and their citizens?
One thing I've noticed around here is that the recent Central American arrivals are much more likely to speak English than are their Hispanic counterparts. That's refreshing.
