How works the Food Stamps program

It's a program provided by the Federal government since 1943 and administrated by the US department of agriculture. It's a financial aid for purchasing food to low income households. 47 millions of Americans receive an average of $134 per month ; this money is now in a card, before it was in printed coupons. In some states, more than 20 % of the population is right now on food stamps.

This money can be used to purchase any prepackaged edible foods, the program does not have nutritional standards. Items in fast food restaurants are ineligible but candies, cookies, sodas are eiligible items...
An average of $72 billion is spent per year on food stamps. Food processing industries benefit from this program ; think of Cargill, Krogger, Pepsi, Kraftfood and others. Walmart is a big beneficiary.
