Buried in Bush's Bird Flu plannign is a call for "community snow days" for which people are being advised to stockpile ten days food. This implies possible 24-7 curfews and closed grocery stores!
Problem is, many people cannot FIND, AFFORD, or TRANSPORT ten days food, especially if they have no car or are on fixed incomes. A lot of people in the inner city live paycheck to paycheck and cannot afford to suddenly buy two weeks extra food.
In addition, poor neighborhoods would be more likely than rich ones to be locked down in the 'real world."
