Practically speaking, an EBT cancellation is not likely to happen because America has always been awash in food, and one of our biggest agribusiness problems is too much food.
Since FDR, the government has purchased and (expensively) warehoused vast amounts of food that eventually rots. If EBT fails, no problem, the government just declares that EBT holders, instead of getting their food via retail distribution, get it issued to them by government food warehouses. Remember Reagan’s cheese giveaway? It saved the government millions of dollars.
A much greater threat to our food supply is if something very bad (like a strike) happens to our railroads. They transfer such *vast* quantities of food and merchandise continually, that a single day of them not operating could cost our economy a half billion dollars. And another half billion dollars every day thereafter.
The next big problem is a massive natural disaster, most likely either a massive California earthquake or a massive New Madrid area earthquake.
Close behind them would be a super tidal wave that devastated one or the other of our coasts.
There are no more of those vast warehouses of food. They did away with them several years ago. They don’t eve keep strategic stores of grain any more.
