We need more representative people in positions of power. But rich white men don't like sharing their power much
Unfortunately I am not sure that insisting on concepts like ' White privilege' being understood and taken on board is particularly useful. This is because many people in power are completely aware of this idea and know that this exists. However whilst they may not overtly want to take anything away from anyone (though those who are openly and overtly racist do do want that) most of them definitely don't want to give anything up either.
So for instance (and I am going to be completely honest here) I know full well that many children for BAME backgrounds struggle to get good jobs because of lack of knowledge of how to build contacts and networking etc and lack of access, even if they do know how in theory. This is all clear and unfair I know but it won't stop me trying to help my son get a job through friends etc if I can. That this taking an opportunity away from a less privileged child is probably true but I put my child's success and wellbeing above that of anyone else's (notwithstanding his white privilege).
I would also help a friend's child, black or white, above a stranger's child (all other things being equal of course) and I can't see that changing much at all. If a lot of my friends are of a BAME background that may not be a problem but if they are mostly white, it definitely is
I imagine most people in power want to protect that power and privilege so they share power only with people like themselves, or people they know and think they can trust. That is how humans work. I can only think of two ways past this (but am open to other ideas):
More close mixing, friendships, marriages between cultures and races (hate that word) leading to fewer perceived differences between people . This 'multi cultural' idea was seen as a good solution in principle the 80s and 90s but many people have come to see this doesn't work as well as we might have wanted it to . After all why should minority groups have to rely on the 'largesse' of more privileged citizens to give them a leg up to power . It puts them in a position of inferiority (at least at first) and I can see it would often be humiliating. Plus see my point about people not really wanting to give up stuff if they can help it.
The other way to stop this is with legislation and regulation and things like affirmative action. I don't object to those in principle either though I can see how if this affected my child personally I really wouldn't like it.
It is a difficult problem and I wish I could see a way through it. Unfortunately as I have got older, I can't see things changing without some sort of violent revolution. Though from what I can tell, revolutions rarely result in more equality, just in with a reversal of power or the status quo being maintained, neither of which is ideal, though I can see how a reversal of who holds the power is a very very tempting aim for those who have had so little for so long.
