Maybe it's something about the cold weather/caution as a people, Protestant/Lutheran/Calvinist cultural restraint, or factors along those lines, but I have relatively more confidence that this country will not squander and flush the money from this resource down the toilet like some other countries. (at least under the country's political leadership that has given an observable track record with the oil resource as an example)
Maybe it's that they can manage the expectations of their people not to suddenly want to get rich and live off of mineral resources and nothing else. Like some other countries have fallen into the trap of.
