While your first point (parents taking more responsibility) is certainly true, there's really nothing a black person can do about the fact that his or her parents were irresponsible. So a given young black person is not at fault at all for this particular disadvantage. But if this particular person gets an education, it is more likely that this person will be a more responsible parent. Since we can't do anything about the irresponsible parents, we can at least try to make sure the next generation of parents are more responsible.
I wholeheartedly agree with the parts about idolizing the wrong stars, hanging with the wrong crowd, and ESPECIALLY the part about teaching the value of an education and the part about blacks pressuring other blacks not to succeed. Mizango and I discuss this all the time, and I've had this discussion a lot with my older brother, my friends, and pretty much every other black person who's in college.
Every point you mentioned (even the part about the parents) pretty much sums up what "black people" hate most about "niggas" (to use Chris Rock's famous terminology). The part about the parents just happen to be 100% out of our control. It's decided at our birth and there's nothing we can do about it.
The reasoning behind these black scholarships is the fact that there is a large and obvious gap in education between blacks and whites. This can be perceived as an inequality that needs to be fixed. White people hate when this is brought up, but yes, this is partially related to how blacks were treated in the past. No, I'm not saying black people should blame all of their problems on their environment or on white people. Any black person in my generation has all the same opportunities I had. But it's undeniable that the reason a disproportionately large number of black people are born into disadvantaged situations is partially related to how we were treated in the past. Just as I hate it when black people blame their problems on what white people did in the past, I also hate it when white people act like what was done to us in the past has absolutely nothing to do whatsoever with our situation right now.
Since we have what is perceived to be a large inequality, and it is partially related to what was unfairly done to us in the past, I can sort of see why people seem to have this "throw money at black students" mindset. I'm not saying I agree with it, I'm saying I can sort of understand their reasoning.
I'm a black guy who grew up in poverty in a bad neighborhood. My mother was a crack addict who did drugs even while pregnant. I ended up living with an abusive grandmother (still in poverty in a bad neighborhood). In addition, I have learning disabilities. So I was pretty much one of the most disadvantaged people you could think of (or at least as disadvantaged as an American can be). Yet, I managed to make it to college and I did make deans list four semesters in a row despite my learning disabilities/two jobs/family situations/etc. So yeah, I personally agree with you, Sepukku. I've seen personally that a disadvantaged person can rise above their situation and be successful, and end the cycle of poverty. I've seen how the bad decisions a person makes is what causes them to be poor (and hence their poor lifestyles are a matter of personal responsibility).
But some could argue that the best way to change these things is to increase the education level in black communities, which is why they give so many opportunities to them. So again, although I don't necessarily agree with them, I understand their reasoning. It's not exactly easy for a person coming from certain backgrounds and has never seen anyone in their life go to college and be successful to be the first one to break the cycle. It took an extremely dramatic event in my life for me to even consider doing anything other than hanging out with thugs/drug dealers and smoking weed/fighting all day. If that had never happened, I'd probably be in jail right now, with everyone else I used to hang out with. And if it wasn't for the extra opportunities and money given to me, it's a lot less likely that I'd be where I am now. So yes, the extra opportunities given to me certainly made a huge difference. But if I hadn't had these opportunities, then it although it would have been much harder to make it to where I am today, it would have still been possible and I'd still blame any failures on myself.
