Haitians aren't Catholic. They're a Satanic, syncretized hybrid of voodoo and novus ordoism.
Catholicism was in the Haitian constitution as its official state religion until 1987, when at the request of the conciliar church it was removed as the state religion.
Between 80 and 85% of Haitians are baptized Catholics.
But many of the Haitian people incorporate voodoo into their practicing of "Catholicism", which, ipso facto, doesn't make it Catholic.
The fact that they were baptized Catholic, and their own constitution made Catholicism the official state religion, but the Haitian people still practiced a Satanic voodoo mixed with ostensible "Catholicism" (Novus Ordoism), cursed them as a people. God initially blessed them with Catholicism and a government that instituted the true Faith as the official national religion, but the Haitian people still turned their backs on God and the Faith. They embraced Satan through spiritualism and rituals.
It's similar to the Jєωs abandoning God many times after He revealed Himself to them, but they continued to worship Moloch and Remphan and Baal and other false entities and make void sacrifices to them.
The US was never a Catholic nation, nor was it founded on Catholic principles per se, so its sin is not the same as apostasy.
Try growing a brain and using critical thinking, you might understand the parallels of the Haitians and Jєωs, and how God tells us that more is expected from people to whom He has revealed Himself more, and if they abandon Him, they will be cursed more.
Is the USA physically chastised for the daily 4000 abortions, the financing/spreading of population control throughout the world (more abortions and contraceptives), immorality, divorce, breakup of the family? It does not look like they have received any physical chastisement to me.
Another fallacy in thinking. Just because it hasn't happened yet doesn't mean it won't happen.
