The plain fact is that no government entity, nor probably all of the government entities, can provide food and water for millions of people even once, much less over several days or weeks. When the roads are flooded and debris is everywhere, you can’t move in the thousands of truck loads of logistics required. It’s impossible. People must take care of themselves. The limited amount of supplies that can be brought in should be for those who lost everything, not those who have a roof over their heads but didn’t prepare.
The restaurants and grocery stores, however, are all open and fully stocked. And the streets are crowded with trucks of all sizes making deliveries of food and other essentials to these stores. Private industry has won the day in this place -- that's for sure.
