well i don't really get what you are saying...i do understand that import taxes are high (i assume there are even import taxes from products within the EU, though not as high as out of the EU), but there is a reason for that - the people are stuck on the island, so the country as a whole can increase the taxes and people will continue to buy, whether it is from the EU or not...
in the US, the fact that there are so many breeders, suppliers, wholesalers, and local choices to make overall do not allow the government to impose a ridiculously high tax level...
i don't really know what i'm trying to say..i guess my point was that even in the US, the price difference you see inland vs. on islands is REALLY, REALLY drastic....so it makes sense, even subtracting EU/non-EU taxes from the equation, that island countries/continents, where people are in an essence STUCK with what they have, will cost much more money
