I do not believe that the generals one has, or the color of ones skin, has anything whatsoever to do with thier ability to be self sufficient or to ecxel above their peers.
Then you live a magical, fairy tale life. Because being not-white, stupid, living in a bad neighborhood, being prejudged by every fucking person you meet and possibly having a shit family are all significant barriers to success, or alternatively, risk factors for becoming the poster child you hold up as your example. The whole try-hard stars-in-your-eyes is unrealistic at best, intentionally biased at worst. Yeah some people pulled themselves up by their boot straps. And because they're the exception to the rule, they're the rule?
Why do YOU feel that these things have real influence?
Because I've grown up in a lot of different places, and associated with a broad cross-section of wealth, race and culture? I'm not going to pull out the "i have black friends" because I don't. But I've gone from seeing what privileged living is like one minute, to hanging out with people at or below the poverty line. (Which would surprise you how high it is.) I've worked with the homeless, I've handed out food to people on food stamps. Some of them were so stupidly grateful it'd be bring tears to your eyes if you're not a total fucking bastard in your heart. I've seen the difference it can make it in people's lives and I've walked a while in other people's shoes, hung out in their houses, heard their struggles.
But the short answer is because I actually care. There but for the grace of god could I be these people and have the stress they do. And I believe the best way you can help them is to help their kids get better educations, get better jobs and see a different life for themselves, and make sure their parents can put food on the table every night until they're adults.
