There is no comparison between the UK economy and the Norwegian economy; the Norwegian workforce is less than 3 million compared to over 30 million for the UK. The economic activities which earn money for the two nations are starkly different (the public sector in Norway is so large it would no doubt be called Stalinism by many of the Free Market Everything Brexiteers) so whatever was said by whom to whom is irrelevant to the British debate, even if everything this woman from a small agrarian party is true and that the warnings about damage to the Norwegian economy were so greatly exaggerated, it doesn't follow that similar warnings can be ignored vis-à-vis the UK. Because a boy cried wolf doesn't mean it's safe to ignore the bear behind you.
