Yet, even in the Nordic countries you have McDonalds and BurgerKing, the sheer definitions of cheap junk food.

[duelingjello]

You're conflating "cheap" as price with value ((quality & quantity)/price). Junk is still too expensive if costs too much. Jack in the Box is terrible food but the location just south of the Googleplex on Shoreline has outrageously high prices ($20-25 average with tax for a male late teenager or large adult male). That's low value crap. If it were monetarily-cheap, in addition to nutritionally-cheap, then it might make sense every now and then.
