I would think there is perspective that sets Finland (or scandinavia) quite different from USA. Even if Finns have very little visible "generational wealth" in the scene (at least seems to me), what we have here is social security system.
It is not wealth, in ways of luxury of having huge funds at disposal, social connections and whatever, but it really is this safety net of some sort, that one can fail miserably in life, in just about every aspect of it, and still trust it'll be all right.
My own background is at some sort of (Finnish standard) very normal lower-middle-class, totally normal family. Salaries combined with seemingly endless debt enable normal life of two parents and kids named with most popular names of each year of birth. Hah. No cultural ambitions, no business ambitions whatsoever. In other hand, there is no dysfunction and no serious opposition of someone heading totally opposite direction than everybody else.
Someone might have generational wealth, but I do wonder how big role it is within work in general? I remember reading Jojo Hiroshige interview where he dismissed Juntaro for being from wealthy family and because of that habit to "make a mess and not clean it up". This habit of making mess and have funds to do it, may have resulted the exceptional art?
