Rules for now:
Finland's population is ~5 million and ethnically/culturally homogeneous. It's relatively easy to swing things around at such small scale. Also, being homeless means being frozen dead most of the year over there. Still a very good thing, but their recipes can't be applied in a snap, not unless you're ready to pay as much tax as the Finns do (hint: it's huge amounts).
