"Norway collected about $1.46 billion on its wealth tax in 2019. But the exodus of the wealthy will result in an estimated $594 million in lost revenue."
ie. Status quo for the Wealth Tax, that exists, is +1.46 billion, it was projected to increase by ca 10% due to the tax hike, but instead trends towards decreasing to 0.87 billion, ie a loss of 594 million vs current tax income from the (lower) wealth tax
