Let's think about some poor, uneducated white kids living in a trailer park without an internet connection. What should they feel when they hear of programs like this? "I'm not important enough to help, because people who look like me already have good jobs?" How should they feel about the myriad of programs and scholarships which explicitly exclude them?
At this point, being black isn't a disadvantage in-and-of-itself. Being poor is a disadvantage, and blacks are more likely to be born poor due in no small part to slavery. But all things being equal, being a poor white person is more difficult than being a poor black person.
And they shouldn't be excluded.
