It's about finding under-valued opportunities, I'd imagine.

I assume that minority-, woman-, or veteran-owned businesses are similarly risky compared to businesses owned by white males. (Perhaps they're even less risky in some industries due to quotas, etc.) If these disadvantaged businesses are getting fewer loans because the bank managers are discriminating, it could be an opportunity for Wal Mart to make some money where big banks aren't.

Quotas are illegal. Some public projects have goals but those aren't firm (and are regularly waived).
