Norway has many great ideas but this isn’t one of them
I’ve had friendships ruined because one party earned significantly more/less than the other and this was accidentally disclosed.
For a government to make this highly valuable and personal information available to the public strikes me as utterly dystopian.
In every society, there’s a tradeoff between the individual and the collective, and I think it all works better when it’s heavily skewed towards the individual. Society has no moral right to nose around in one’s bank account.
