Assuming that's true, by ramping up public borrowing (most likely), increased tax receipts from increased employment (less likely) or seigniorage (least likely).
Regarding the personal allowance increase, I'm sad that the article glossed over this. I was really impressed that it was a tax cut for both the top bracket and "everyone". I wonder how the Danes would react if it was only an increase to the allowance, without the top bracket cut?
Without increasing other taxes, or reducing spending?
Where's the extra money coming from?
