It's a simple inference if you've ever looked into starting your own business or have talked with business owners. Minorities and women are given preferential treatment when it comes to taxation and bidding on government contracts. I know several "family" businesses that are "run" by the man of the house but "licensed" by the woman of the house specifically for tax purposes. Or, licensed by the "minority" woman, if you can squeeze both benefits into play.
I think this is common knowledge in the business community. I know it rang true when our "white" family used to own and operate a business.
Actually it's worse than this. They actively attempt to get you to manipulate the program in such a way. For example, I took some SBA courses that our local community college was having. Once they found out my wife was Korean, they tried real hard for me to get her to attend the classes and apply for a SBA loan.
They did not understand that I was just there to get some business knowledge, not to apply for a handout. It really offended me. It reminded me of an article I read not too long ago about how the food stamp folks are advertising for new people
