This humbleness can be seen everywhere. Btw, you are thanking (sic!)Peterthegreat for his posts? Yes, yes do it, it is so nice. Swedes are gods as you know.
I think that after the Civil War, many of the socialists from Finland fled to America. So the deal with many of the early 20th century Finnish immigrants was actually that they weren't humble, so to say . So as soon as they got to America they started to organise strikes and stuff to better the working conditions and salaries, which led to them having a bad reputation as trouble makers, which meant that people wouldn't hire them.
