"A few millions in the bank" for hundreds of thousands or million of people would already make a nordic country the king of lesser inequality - unless (as the parent says, don't know it's true) it's tied up in company assets (and perhaps they use them as company perks even in one-person companies, to avoid the tax, thus masking better equality at the individual level).
