Even if you do, the past is a complicated thing. Plenty of people are nostalgic to the USSR, and many of them might very well have been better off under communism.

That said, in terms of standards of living, I think it's fair to say the Nordic countries were comparing themselves to the US way more than the Soviet Union in the postwar era. The Finns would rather be dead than associated with the Soviets, which many of them demonstrated quite forcefully during the war. As for the other Nordic countries, the Marshall Plan certainly didn't weaken the admiration of the US.

If anything, what made the Nordic model such a success was the decision to look away from the Soviets - the influence the Soviet Union had over European socialist parties somehow didn't catch on in the North. Marxist-Leninist parties existed (and still exist), but they were mostly sidelined (to a degree that is, in all fairness, problematic in its own right).
