I get the idea that small fractions of bigger pies can be more than a big fraction of a small pie. And I can assure you that Scandinavians are well aware of tax revenue optimisation.
I will even say that it is very likely that they are already near the optimum for their country. The reason is simply that if every time you increase taxes and notice revenue goes down, you will naturally reverse it. Society moves through incremental changes.

That isn't necessarily how it works.
Suppose you increase taxes and revenue goes up by 5%, but growth goes down. Now in ten years your economy has grown by 2.5%/year instead of 3.5%/year or more, so your tax base is >10% lower than it would have been in the alternative but at no point is is less than it was the year before.
