Europeans for the longest time were quite smug towards the US electorate on various domestic issues, ignorant of demographics.
Europe until recently was 90%/10% White/Minority, allowing for many "progressive" social programs effective at keeping social cohesion, and largely low crime great communities with a high quality of living due to it(country) being largely homogeneous. All this with a strong state bankrolled by higher taxes, and by the benevolent US's security aparatus, thus allowing them to skim on defense costs.
The latest figure I could find was it being
14% Minority in 2002, wouldn't be surprised if it's much higher today, but race stats are cleansed off search engines and wikipedia, hard to find.
Europe in many parts IMHO still have a great chance at fighting against this demographic tide, it's the motherland, pride of ancestors looking down upon it. And the demographics are much more favorable to deal with, at least compared to other western nations like Australia, Canada, and I hate to say it but the USA
But they gotta act sooner rather than later, many urban areas are done for, higher fertile indigenous european groups like the poor and working class are priced out, and the high income earners that aren't, don't produce. Which results in urban under-18 demos largely minority-majority, as seen in schools, due to high breeding invaders, not priced out as they are supported by the government and their own insular communities.
