The difference is that it actually won't,I disagree. I think having more companies (especially successful ones) founded by black and hispanic founders will help everyone broadly, for this reason: It will provide young, potential founders, who might not otherwise have pursued entrepreneurship at all, with positive role models, and will show them actual live examples of how success can be achieved.
My feeling is that this promotes entrepreneurship in general among increasingly larger portions of the overall population... and if you believe that technological progress in general is basically a net positive for humanity (a position which I admit is not without controversy, BTW, although I personally adhere to it) then this is a Good Thing. More smart people working on new ideas, and creating things to solve problems? Yeah, I can accept some private companies engaging in a little "affirmative action" if it supports that.
is to make these sorts of initiatives open to anyone disadvantaged (such as the poor), and invest in programs targeted at children in minority communities.
Having grown up "white but dirt poor" I mostly agree with you, in the sense that I think addressing poverty - regardless of race - is also a valuable thing. I'm just not sure one approach is more or less important than the other. I think both are valuable things to do.
