In the majority of cases I would agree.
Saying that some races have been fudgeed up beyond all recognition by others
The only way that race has a chance of leading a normal life is a quota system as the incumbent will fight to protect their own
There's not much evidence for this approach actually working.
Equality of Opportunity, not Equality of Outcome.
Is there equality of opportunity though? Look at South Africa - their national rugby and cricket teams were traditionally filled with white blokes who had mostly been private schooled. Brining in a quota system encourages those filling representative teams at various age groups to look at the talent in other less 'desirable' areas. You only get opportunity if you get seen.
I think you have to try.
When I went to SA for the first time in the early 2000's I was always amazed by the clientele in the business class lounges at airports. All white (perhaps not overly surprising) and no women on most occasions.
These days whilst definitely not 50/50, there is a percentage of blacks and many more women.
Now people will crap on about tribes and Africa but no one can not say that the blacks were fudgeed over completely by the whites.
Fixing that fudgeed upmsystem unfortunately requires quotas because the whites are not going to give that up otherwise. They are not going to hire blacks or even women into management roles etc unless told they have to do so.
Now because it is so fudgeed up that doesn't happen overnight as you have to do it slowly or everything falls down. It's not done in a generation or even two but gradually you will have a black educated middle class coming through.
The question is if the blacks in the slums of Alexandra will wait two generations. Probably not and if I was living there I wouldn't wait either
