Assuming we got Danes to run it, yes, I’d want their universal healthcare system too.

Is it that different? Lots of low skilled people who are generalized to be a threat to the nation.

Immigrants to the US are mostly from the Americas, so Mexico, Guatemala, Honduras, Venezuela, etc. The US also has people fleeing war, such as Ukrainians.

The main difference is that they are easier to integrate. For instance, immigrants from the Americas speak a romance language, and if they speak Spanish, that's like a second language for the US. Most are also Christians, and yes, it matters because they don't uphold Sharia over local laws. Yes, the US is also getting drug dealers and such, but I bet that a vast majority are there to work and pay their taxes.

Europe has the problem that it took in many people from Africa and Asia, that are harder to integrate, and with many of them fleeing war. And the difficulty here is that people fleeing war have no intention to integrate or even to work for a living if they can get away with subsidies, many intending to return home as soon as possible. Europe also has the issue that it has never been a melting pot, smaller countries in Europe don't have a tradition of cultural diversity, they are unprepared to integrate that many people over a short period of time.

There was also a story recently about Russia apparently fuelling immigration from war zones into Europe, to destabilize the EU and its governments. They also funded “green” NGOs and politicians who succeeded in shutting down shale gas extraction and nuclear power plants, increasing the energy dependence on Russia. I'm guessing their hybrid war is a wild success.

Not to be misunderstood here, I am pro immigration. For example, Germany has been a powerhouse of Europe due in no small part to their generous immigration policies. The population is growing old, and we need people to support society. The “low skilled” classification is a canard. Countries require “low skilled” work as well, and note that unemployment is at an all-time low, US and EU included.

I'll also note that the UK ran xenophobic ads ranting against Poles, Romanians and Bulgarians, as a justification for Brexit. After Brexit, they wanted them back, especially during the pandemic, since “low skilled” Eastern Europeans started going to Germany and other EU countries instead. And immigration actually got worse for them after Brexit, which was ironic, but not unpredictable.
