I'm brazillian, moved to Finland 2 years ago to work here, and can confirm the sentiment.

If you ask a Finn, most people are actually quite harsh to the Finnish government, economy, etc - specially as of recent, since Finland now has one of the worst unemployment rate in EU. But lifestyle here is quite sober, everyone has hobbies and are quite dedicated to them. I guess the Sauna and Avanto culture are the main happiness drivers here, and tbh after experiencing it, I wouldn't change for anything else.
