Nonsense.
I am very aware that the level of immigration has increased and that the countries of origin have changed, especially so as a consequence of Brexit. Which is ironic given the motives for many pushing for it.
There are some, perhaps including yourself, whose local areas have been more impacted by this than others. That tends to colour their judgement.
My view is that these things tend to settle and sort themselves out in time. Changes are inevitable and to resist the inevitable is wasting time and effort. You either moan, bang your head and get angry and upset, or accept and come to terms, or move.
