I am specifically NOT trying to go down "redress historical grievances", only "try to correct for currently existing imbalances".

There's probably also something to be said for having policies trying to get some geographic rebalancing in place as well. But, what I am trying to say is that redressing recent-past wrongs MAY require slight over-compensation.

To make anything other than sweeping generalisations, I would need numbers. Oh so many numbers.
