The French debt plunged them into a cycle of poverty. They were blackmailed to repay France in return for recognition and the ability to trade with third countries.
They were also threatened with the reimposition of slavery. The whole matter is is inexcusable.
Was there corruption, was there mismanagement of taxes and borrowing? Of course. To pretend the original French demands weren't an extreme hardship that set them on the course they would take is spitting in the face of reality.
In modern times they've also had to deal with the IMF, World Bank, and IDB and everyone knows how that goes.
As far as my understanding of economics and finance goes islands will always be at a serious disadvantage in this age.
