You're welcome to challenge the "it's not race, it's poverty" assertion anytime you want by hopping on a flight to Shreveport, Alexandria, or Opelousas, and just walking around. In places like that, where the population is about 50% black, and 50% of the population is under the poverty line, you'll notice that nearly 100% of the non-managerial people working at fast food places are non-white.

I don't know what the appropriate coin-flipping analogy is, but it's like getting heads a lot of times.
