I assume the meaning is that even Michelle Obama, descendant of slaves, was benefiting from racism insofar as the house she was living in was built by slaves.
Maybe, but what you want to do? Knock down a perfectly usable White House and waste money building a new one, just so we can say the President no longer lives in a house built by slaves? The White House was built by slaves. It was wrong, it was racist, it was a crime. But it is too late to reverse it. The While House is already built. Nothing can undo the fact that it was built by slaves. The slaves that built it are long dead, there is no way to help them, there is nothing to do that will do any of them any good. Make sure it is remembered how the White House was built, build a monument to the slave that built there. Put up a plaque to remember it. But it is done and can’t be undone unless someone invents a time machine.
The literal level isn’t where the useful discussion is. It’s not about a physical structure per se, it’s about a nation. It’s not about living in a house per se, it’s about benefiting from past injustice. So – to refrain from the original post, what is she (and what are we) going to do about that?
I don’t know that anything can be done. Unless you have a time machine, you can’t change the past(even if you did have one, there are a whole slew of problems with trying to alter history).
You’re still looking at it very literally. The slavery happened and can’t be undone. The lynching and redlining happened and can’t be undone. But the current injustices that are derived from these things? Those can be undone. The trouble is that the current injustices are much more subtle, institutional things, and perpetuated by largely well-meaning people with no overt racial animus. Nevertheless that’s our responsibility, to wipe out the legacy of slavery, since the slavery itself was already wiped out by previous generations.
EDIT: Your questions about job interviews are actually a great example of how we do this today.
