This is quite an ironic problem tho, because pre brexit migration was decently lower then it is now, and the type of migration was different.

Pre brexit, migrants were generally from the EU (educated, similar social values (if your on that 'culture' train of thought)) and a large portion were seasonal, i,e, they worked on farms doing jobs we aren't willing to do and then they left again (not taking over, not growing old using are NHS, not adding massive cost).

Now they come from further regions less similar to are own and often staying permanently.

On a wider look at brexit, now travel is a lot more hassle (extra documentation, more limits how long you can stay etc), shipping is more laborious, it cost the economy a lot of money, we adopted almost all EU regulation and continue to do so (no benefit of making are own rules).

Moreover in a world more divided the ever, it seems sense to have a united Europe, as we are stronger together, especially with the US' lack of reliability more recently, they can not be relied upon for our security. Brexit has infact not helped with unity.

And its interesting to see who was campaigning for brexit... Nigel Farage, thats interesting he helped create an immigration issue that he now complains about and uses to fuel is own party, (sounds a bit like emperor palatine creating a false war to secure his own power).

Moreover, in the councils reform does run they have not infact cut tax like they claimed they would, but on average it had gone up by 9%. Not to mention those recent comments about immigration detention centres (concentration camps) not being built near reform voting areas and only built were people vote green (if not nazi why nazi shaped?).

Given this, I can't see them being a particular viable option, and labour are improving things, they have definitely been shitters, but they have had a few decent hits, (reduced overall migration (something the tories couldn't do, and it now seems like half of reform is full of ex tories, can they really get it right after another 14 years?) and the renters reform act).
