Oh, everyone knows why the food deserts are there; often the only people who will open businesses in those areas are foreign newcomers (Asians, Hispanics) - one was robbed by Michael Brown before he was shot attacking the cop in Ferguson. Those businesses aren’t cheap to shop in, not just because of the high losses from theft but also because they are often the only taxable entity on the block (in areas dense with government housing).
I completely didn't take that into account, that would be correct. What you said, all exactly true.
