Most "wealthy" Russian parents do not have £££££££ and golden visas.
"Wealthy" is of course relative, but most of the Russians I know have been living in the UK a number of years (often decades) and have built lives and lifestyles here.
The wealthiest among the ones I know (and again, everyone's definition of "wealth" varies) are well off because they are part of a double income couple with jobs such as medical consultant, engineer, architect, maybe financial services.
ie, above average income but NOT mansion-in-Chelsea-and-a-super-yaght-rich.
The small minority (the elite of the elite) who do have golden visas have been welcomed into the UK. They are not just mates with Putin, they are friends with British senior politicians and our own elite (so I am not sure how school bursars can be held responsible for policing their wealth when the institutions actually responsible didn't). These people are the problem but they do NOT represent ordinary Russians in the UK.
It would be like an American assuming that as a British citizen, you must be pally with the queen.
I am scared of the knee-jerk racism that always emerges after a major world event.
Islamophobia after terrorist incidents.
A wave of anti-semitism after the Israeli government does something we disagree with.
In early 2020, there were racist attacks directed at Asian people because some knuckle draggers held random people personally responsible for Wuhan, solely on account of their ethnicity.
And now no doubt we'll see some entirely innocent Russians picked on by idiots who think they are Expressing solidarity with Ukraine, whereas in fact they are just stupid racist aresholes who couldn't find the place on a map.
At the very least, could we be careful about how we discuss things with our children?
Ie, blaming Putin and his cronies instead of demonising a whole nationality?
