Where you say “sophisticated”, I might say corrupt and likely criminal.
Not all activities in the financial sector are destructive, but the sector as a whole has a tendency to reward destructive activity.
You might like Michael Hudson's comment: "when left-wingers–or people who call themselves left-wingers, they’re really not left-wingers at all; they’re, I don’t know what, post-left–very few people who call themselves left-wingers distinguish between industrial capitalism and finance capitalism."
As an aside, "sophisticated" sounds like an applause word which is not intended: I think overall the benefits outweigh the harms for Germany to have its business decisions made more by industrialists than financiers.
