It's irrelevant.
Each Nordic country is different.
Sweden and Denmark's national pension pays out largely similar to American Social Security ($1k-$3k/month)
Finland's appears to cap at around $1.5k/month and the rest is on you.
Norway's is very generous (114% of monthly income), but it's easy to be generous when you are also a petro-state and your pension is backed by the National Oil Fund.
In all these pensions, you have to contribute to the state pension fund in order to receive more than the bare mimimim ($1k/month) at a level largely comparable to Social Security deductions.
It honestly isn't that different than the US SSA, especially factoring in CoL which is California or MA level but average wages are around $30-$50k nominal
The "Nordic Model" that became vogue in American political discourse is the Norwegian model, which is almost entirely subsidized by oil. We may as well copy Saudi's social welfare program then (on a separate note it is actually pretty generous after massive concessions were given after the Arab Spring).
