Norwegian here. Some filthy rich are moving their assets or even themselves to tax havens. F.ex. Norways richest man, the oil and shipping millionaire John Fredriksen made himself a Cypriot a few years ago. Some other are transferring their assets to their children who live in f.ex. Switzerland. But overall I don't think capital flight is a huge issue.
