Your analogy is terrible, by the way. The Hebrews emigrated to Egypt voluntarily. The African ancestors of the Haitians did not voluntarily emigrate to Haiti. The Hebrews were miraculously liberated from slavery by direct divine intervention, led by divinely appointed prophets to their own ancestral homeland and given a full set of laws and institutions by God himself. The Haitians have not had these benefits.
I think you left out a bit of the history. The "Hebrews" were overrun by the Romans and most of what was in their "ancestral homeland" was destroyed. As recently as the mid-19th century there was next to nothing there as can be seen by reading Mark Twain's account in Innocents Abroad. Things are different today. The people did that.
