The problem with your examples is that they support the idea that forcible immigration isn't a good thing and has negative effects. Consider that most of the Chinese that came prior to Civil Rights opening up immigration didn't prosper but instead were generally stuck living in poverty in Chinatowns or on farms. The model minority idea was started by a group of largely self-selected Asian immigrants who were among the brightest and most ambitious who voluntarily came here starting in the 1960's. Not the descendents of railroad workers from the 1900. As for West African coolies consider how much of a basket case many Carribean economies are, look at Haiti which is almost completely made up of the descendants of Africans forcibly brought there by the French. Colonialism and slavery certainly had a negative effect on them.
