Brexit has blocked off Europeans from Britain. It's difficult to move or work there now.
Nothing is going to change for the UK except accelerated demographic change.
No more Europeans to off-set this.
It seems like the native people are "helpless". People are saying that, on average, they can't make enough babies, they need immigration to thrive, and the native people can't stop the invasion by the third world or repatriate those that have already invaded. They can't even name, much less fight against, those that are producing movies, tv shows, and commercials promoting miscegenation, setting the cultural agenda, erasing their history, and running the NGOs that are funding the invasion.
If someone says pay native people to have children, that's a bad idea or impossible, despite the fact that they give the 3rd world invaders the native population's tax dollars.
Anything to stop the colonization of Europe by the 3rd world is "racist" and struck down immediately by those making the tv shows, commercials, subverting the culture etc...
Then, Brexit, which, at least to Americans, was thought to be a movement to give the UK back a degree of autonomy smothered by the EU, keeps out what some believe the UK's possibly only demographic hope, which is the immigration of other Europeans, because the native people can't reproduce or kick out non-European 3rd world invaders?
It seems like funding native Europeans to have children, clamping down on third world immigration, repatriating the bulk of 3rd world immigrants, clamping down on those in the media that are working against the native population, etc... are all "impossible" or "impractical" but everything counter to the native population's interests is all feasible.
The entirely possible and necessary is perceived as impossible.
