Norway

Norway is with 385.000 km2 and only 5,4M people one of the thinnest populated countries in Europe. Norwegians are the 4th richest per capita in the world, most because of the oil, which makes Norway the biggest producer per capita outside the middle East.
Norway is constitutional monarchy and one of the best functioning and safest democracies in the world. The country ranks high on the happiness scale and has one of the lowest crime rates in the world.
Norway has one of the best public education systems in the world, which is, of course, free for EU-citizens.
