I am in the UK. I am using "black" as shorthand for non-white ethnic minorities who suffer racism.
I do not need statistics on outcomes to know that most if not all black people suffer from racism, not least as I know that even people who explicitily try not to be racist, like me, can be racist unintentionally. One can suffer racism and do perfectly well, the two are not mutually exclusive.
I have never said that racism is a worse problem than wealth inequality or sexism. I think poverty is the worse problem, then quite possibly sex then race, but I'm not sure and it isn't a competition.
"Does a black person have ‘privilege’ over a Bangladeshi person?" In Jamaica - probably, in Bangladesh, probably not. In the UK it probably depends on the precise location and context.
Privilege is not simply about whether you have a job. Of course other factors relate to privilege not just employment status.
I do not badly want anything but the truth. The truth is that Kwasi Kwartang is simultaneously extremely privileged compared to huge swathes of the country, whilst underprivileged when you assess him on skin colour and nothing more.
If you cannot see that (by definition) a white 3rd generation unemployed man can have white privilege over non-whites whilst simultaneously being massively underprivileged and worthy of as much help as anyone else vulnerable in society then I can;t help you.
None of the above means that the word privilege is necessarily the best word to explain these concepts, especially to a 3rd generation unemployed man.
