What would you call it then?

For me personally, I would try to talk about the specific issues and describe them, as you did in the second part of your comment. I understand there is a definitely place for using a simple phrase to characterize a larger pattern of inequality. Even using dramatic, colorful phrases which capture the imagination also have their place in the world.

Edit: I'm not trying to change your approach, I'm just being blunt about my opinions. I appreciate your open mindedness.

But the problem is systemic and it needs to be named directly. Skirting around the edges of the problem, trying to be indirect, will not be effective.
