I think this debate isn't about race and immigration - it's about greedy employers and organisations wanting to recruit foreign workers on low wages and treat them badly with the "carrot" of permanent residency.
Take academia and universities.
The new threshold is above that of a postdoc salary (that's a role after a PhD).
Not surprisingly, lots of white liberal senior academics complaining about this, it's all "so cruel and heartless" and they all are ardently looking for photographs of a non-white female scientist to Tweet, to show how cruel the system is. "What a loss to British science!".
These are the same senior academics who basically shove scientists from India and China into 70 hour weeks of processing chemicals to produce results for them (whilst the white middle class academics go to social events and networking events).
They basically get indentured servants as they can threaten to take their visas away if they don't do as they are told.
They don't give a fuck about science or knowledge or non-white people. They care about their cheap labour drying up. Their social group will be entirely comprised of white faces (even in a very international environment).
Carer is one of THE most important jobs in society. Again, why not raise the salary and conditions? What are the profits of nursing home bosses?
Who is profiting from the cheap labour coming over?
I think some wealthy people are "playing both sides of the equation" - encouraging desperate people to immigrate, suggest they move to areas with elevated racial tension (away from wealthy white people) profit from them, then enjoy them being criticised.
Universities have offices devoted to recruiting foreign students (and suggest they can work afterwards). It's ALL profit. They sell Masters courses with huge fees (going to the university).
The world is levelling up.
Many countries have a burgeoning middle class now, and work opportunities galore. People can move cities to the capital or neighbouring countries for a change of scene (and most people do - the countries with the most refugees are Uganda, Pakistan, and Turkey last I heard).
People say Suella Braverman is cruel and racist (and of course like to remind everyone due to her dark skin colour she's "not and will never actually be a proper British person" despite being born here with a Cambridge degree).
I think it's incredibly cruel and racist to entice workers, encourage them with a "lottery ticket" of permanent residency, then exploit them and get them to run the gauntlet of racism and uncertainty over their living status, whilst some greedy university bosses and senior organisations wipe their grubby greedy hands.
