The UK should just compile a list of technologies/amenities/infrastructure that they gave Jamaica and call it even. Things like running water, concrete construction, written language, rule of law, etc etc etc.

When determining whether a people deserve reparations for colonialism, the question must be asked: "Where would these people be right now if they hadn't been colonized? Would they be better off or worse off?"

If the answer is "Worse off" then they aren't owed any reparations.
