a person should be embarrassed if he is doing something wrong…so if you think it is fine to feed your family with foodstamps while you are learning in kollel, seems to me there is no cause to be embarrassed.
Personally, I don’t think it’s right to use foodstamps as a “plan” for long-term survival. Foodstamps should be used to get by when a person has no other choice, just like tzedakah.
