Germanic and Nordic countries are more orderly, stoic, organized, less emotional. It goes hand in hand with political and economic stability. Great to make money, but sucks living around stiff people.
Romans countries, and basically farther south one goes, are more emotional, impulsive, less orderly, more laid back which effects politics and economy in negative way. People are lively, animated, you know if they like you or not, can give you energy and fun to be around.
Language has nothing to do with politics or economy.
Though is influenced by people speaking with their emotions. I would rather listen to Gabriela talking in French or Italian than listen to Helga from Sviden,...unless she speaks Italian.
