That's inaccurate at best about the Nordics. Norway, yes, and Denmark to some degree. Neither Finland or Sweden have or had any significant oil and gas reserves, but built their economies on industry (and mining to some extent).
Agreed, but mining has historically been a big in Sweden (part of the reason why so many minerals were named by Swedish scientists). While we now have focus on other areas it has always been an important part of the economy.
