I’m about as left as they come (I think though that doesn’t make me “soft” or a Labour fan) and I also worked for the Home Office in immigration control for 12 years (proud to do so).
It is not racist to have immigration control.
Immigration control is one of the only measures that protects the (now failing) welfare state - I wouldn’t want the collapse of the welfare state because it’s one of the good things we have.
The Refugee Convention didn’t come into existence to help people flee war torn countries - it came into existence to protect people from State persecution (and non-State actors acting as if they were the State).
The HR convention came later and protects agreed upon rights against State killing in most circumstances, torture, detention, protects against unfair trials and State interference in marriage, family and private life etc.
Subsequent international conventions protect Internally displaced persons (IDPs) from warm torn countries but offers none of the protections that the “Refugee Convention” offers in terms of settlement, family reunion or work status.
The UK will, I hope, always provide international protection.
It is however not the case that someone travelling via any European country from whichever country they claim to be fleeing from needs to claim in the UK and they don’t have an automatic “right” to do so.
Before Brexit, those who arrived from Europe were returned within days to the country they first arrived in and claimed asylum under the Dublin Convention.
The Rwanda effort was never going to make it past the courts - and was a pointless effort at being a deterrent.
To me, the UK has options with this idea of taking assets that might be more nuanced than “we will take everything valuable” (and The Guardian is extremely biased in reporting immigration matters - I recall its reporting on matters I knew about when I worked for the HO you and it loves exaggerating the facts but that’s another day’s work.
I cannot see anything cruel or racist about saying to someone coming via Europe to claim asylum here that they are “shopping” for a place to live and their assets can be taken to fund their time here - there can be added caveats (if you are granted asylum x if not y).
Apparently the government are also tightening settlement conditions for those granted asylum - making it 20 years before they can remain permanently and the expectation that if the country of origin becomes safe that they return there - that’s far more controversial to me than taking assets (which is more obviously a deterrent action).
As for the emotional part of separating from assets - if my daughter (severely disabled) needed treatment or a safe place because the UK became unsafe for her there is nothing of monetary value I wouldn’t give for that to happen (sentimentally I would want my first DD’s hair in a locket but they can take the locket). Maybe that’s not the fairest way for life to go but then fuck all is fair - and if I needed safety fame and her they could have anything I could give them.
