This isn't even true (immigration accounts for half of Norway's population growth) but let's take a more extreme example: Sweden, the country with 7th highest quality of life on planet Earth yet every 1 in 11 people is an immigrant. This single case proves your generalization wrong. Every 16th person is a first generation immigrant originating from outside of Europe.
You seem completely ignorant of the fact that we took hundreds of times more immigrants per capita than any country on Earth yet we all dominate the fuck out of ALL of quality of live rankings.
The ethnicities in Norway are recorded as Norwegian 83.2%, other European 8.3%, other 8.5%
Your vision of Norway and the numbers don't lineup. 92.9% of people are white..
Can they even buy a house or do they have to settle for an apartment?
Quality of live might be great in Barcelona if you like to drink and eat and want to work less. But Spain is so small comoared to the US. The US has so much more variety.. deserts, tundra, forests, palm trees, rocky mountains, cities..
What... world do you live in that Europeans* can't do all of that except the last?
> Can they even buy a house or do they have to settle for an apartment?
Of course... wtf? lol 76% of people own their homes in Spain. Home ownership in the US is only 65%...
* Spanish people can go anywhere in the EU with just an ID, no passport needed, just like in the US.
I could pick pretty much any US state over Spain and with a US engineering salary enjoy a vastly better standard of living.
Addendum: used to live in a very wealthy suburb in the US. Said houses are creaky, have constant humidity issues because the mildest of winds would blow out the roof tiles, and have a very low standard of construction coming from other places. More square footage is not indicative of a higher quality of life; many rooms sat mostly empty and did nothing for us.
> Two different states want out and after a vote they arrested the head of state for those regions. The legacy of Franco..
You must be trolling. You literally had a civil war for the same exact reason... Unfortunately, no state allows any subset of itself to secede.
And day to day quality of life has nothing to do with geopolitics for most people. US just simply ranks far lower than Central Europe and the Nordics in these measurements. A lot of it is just city planning and infrastructure.
