I've often thought that a similar factor might help explain why as a group CAribbean Indians in the US seem to be better off than African-Americans with a longer lineage in this country. Of course, there was still a history of slavery on the islands but perhaps the white American can say "At least they were never OUR slaves". Just a thought.
