Culture first, money second. Migration before used to be purely about the improvement of economic factors of living. Now money should be more of a supportive factor rather than defining. From what I experienced, the cultural aspect feels far more important for me. I don't mean just the historic development of the region or number of museums, but a culture in its broad meaning — from people's values and ambitions to general state education and heritage. Often your own culture may feel the best suiting but very often it's just a "first-timer bias".
