I cannot think of one prominent Chinese family that came as indentured. They are very few wealthy Portuguese also but they have massive wealth and do employ other Portuguese...I see nothing wrong with that.
The Chinese and Portuguese came to Guyana as indentures. Most Chinese and Portuguese are at a minimum, middle class. Most Indians are poor.
Of the groups which arrived as indentures Indians have done the WORST. In fact there are many who will claim that the average Indian isn't better off than the average African. The 2001 census suggests that they also remain less educated.
As you cease your silly response and do some digging you will find many of the same forces from the colonial era responsible for this disparity. What is evident is that Indians remained on the estates longer, and so many became trapped in poverty as a result. Together with other ills of estate life.
So cease your racist prattle about Africans and understand that Indians have serious issues too, like being responsible for Guyana having the HIGHEST suicide rate in the WORLD! Happy and successful people do NOT kill themselves.
