You don't want it more by saying you want it more. It's all about your actions, working out harder, or studying more then others etc.
They are helping people in the slums from every race about equally, you don't get more welfare for being Black.
Being black you get advantages when doing things like applying to Medical School.
Most people applying to medical school were able to afford all of 4 year university and are far from the slums.
The Black Swordsman is actually a white guy in black armor in a comic book...
1- So people in the slums just need to work harder, or study more to get out of the slums?
2- Welfare doesn't really help people they way they have it set up, it enables.
3- Businesses do get financial help for hiring people of certain races.
4- I know for a fact that people going through medical school get some insane loans available to them in anticipation that they will make a ton of money and pay it back. It is possible that kids from poorer families have much more stress and real life things to deal with that take them away from their studies, which makes it difficult for them to become doctors and such... but it is still possible. Like you said earlier, if you want it bad enough you will be able to do it. There are plenty of inspirational stories of people overcoming the odds and earning for themselves a better situation.
5- Good to know on the comic book thing. I'm really out of date when it comes to my comic book knowledge. I guess I just don't want it bad enough.
