Agreed. Much of this is dealt with by J. P. Rushton's book. To me, "Spiritual" and cultural are splitting of the same hair. You can apply your comparison of Haiti to the continent of Africa. The West has been dumping billions of dollars, technical advancement, social/economic/police/health/civil-legal and even religious infrastructure and the effect is/has been marginal at best. It took ol-whitey to actually go there lead and do for these people/states to progress yet sadly the ol-whitey "racists", "imperialists", "capitalists" were thrown out (supported by the UN) in favor of reverting back to black leadership, mass expulsions, property annexations etc. only to revert each one back to a state of animalism. There are many books written on this subject but there are a few very good chapters on this subject in his book "Modern Times Revised Edition: The World from the Twenties to the Nineties" by Paul Johnson.
