Positive discrimination, for it to work, needs to be quite strictly applied and there should be some semblence of earning one's keep for the person themselves. Just gifting something to someone that others have to work for really doesn't work and there's heaps of evidence to support that. I know there's some scholarships available for Nungas to do medicine at Adelaide Uni. One or two places are set aside but the candidates still have to do all the entry tests any med students have to do, etc. Don't know all the details but I think the scholarships offer a bit of money for textbooks/equipment and pays for some out-of-hours tuition.
