It’s not just Americans. Can’t we find a European source that describes this is in a complete and EU POV?

Wages in general are much better in the US. But then expenses also tend to be higher, not only health, even the tipping gets crazy expensive. But in the end it’s very personal, what makes you happy? Is it money? Being close to family? Being in your own country? For most people the move would be too troublesome to be worth it, I guess.

That depends a lot of the country. In some EU countries is rather easy and cheap.

Moving abroad is always challenging and not for everyone, some people can’t adapt to a different way of life.

The EU has obviously an interest in getting the UK back in some shape. But I would say that nobody is in a hurry right now. The UK needs to sort itself out, decide what it wants and be consequent and solid about it. There are currently many discussions on the shape and reform of the EU and more people defend the idea of different levels of integration available. From a true federation with single currency in its core, to contries with free border, free movement, common market, but own currency and non-federated. That second tier could be ideal for countries like the UK and Ukraine, at least in the foreseable future.

The motivation might be different but the result is the same, facilitating the Russian regime financial moves.

I have not idea if this is reliable, and I do despise Musk, but, considering that Portugal will soon start destroying mountains for lithium it would at least allow the country to benefit a bit from those lithium mines that by themselves won’t bring much.
