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.

The Jews who rebuilt Israel were led by an extremely well-educated group of Europeans who had enjoyed freedom and economic independence before the rise of fascism. They were not premodern subsistence farmers who were purchased by Turks and Arabs and involuntarily transported overseas - the founders of the state of Israel were sophisticated and accomplished moderns who voluntarily decided to settle in the land of their ancestors and to provide a refuge for those escaping fascism.
What I am going to say refers to a tendancy, not an absolute.
The hebrews/jews had at least a 2,000 year history of surviving by their wits and handling money because in many cases they could not hold land. Their whole religion is very obsessive/compulsive (I am currently browsing through a book on How to Pray as a Jew). It is mind boggling the details of what they must do to be orthodox. They kept their traditions and language and practiced them wherever they went. They also passed religion through the mother which made it more likely the children would learn the traditions.
The Hatians on the other hand were kidnapped from many different part, language groups and cultures in Africa. Slaves were not encouraged to communicate in a common language of their own, and barely educated in the masters language. Slaves survived by being subservient, physically strong, and resistant to disease and physical mistreatment. It shows in the long miserable history with if I remember correctly more than 100 dictators since their bloody revolt.
