I'm just gonna drop that for a long-ass time Finland has been a mostly agrarian economy, and very weak to depression and recession from as far back as the 19th century. It probably wasn't any better off during the Great War, and surely suffered in more than spades in the post-war. And later having the Russian Empire marching all of its Grand Duchy to keep order certainly didn't help investment opportunities in the area. So even if in the last ~5 years since the last episode of revolutionary violence the situation is probably still poor and still very agrarian. And what investment they had is probably pretty low, investors like stability and a low risk of loss, which I think Finland may just be that there.
