It's more like: you're in a certain group, you get hired, and you know that the company that hired you has this policy of prioritizing hiring from your group. You spend your days in that company wondering whether you got are there because you're good at what you do, or merely because you are member of the prioritized group. I wouldn't want to be in such position.
Would you enjoy always wondering whether e.g. people in your team are listening to you because what you're saying is worth saying, or if they are merely humoring you and tolerate you in their team on account of orders from above?
Something like this must do ugly things to one's mind and one's perception of self-worth.
