As @umbrella@lemmy.ml said, the Nordics can only provide the safety nets they do while paying generally high wages while still maintaining enormous profits for their bourgeoisie because they expropriate vast sums from the Global South via Imperialism, manifested in outsourcing manufacturing for pennies and through large loans. They are Landlords in country form.

They aren’t alone in this, of course, the whole of Western Europe generally does it, and the US Empire is the biggest at it.
