This entire thread is ridiculous and reeks of middle class privilege. I understand what OP is trying to teach her kids, but it's impossible to throw in all of the variables that a low-income family faces. Anybody who has replied talking about how they easily spend under the food stamp $$ shame on you! I dare you to walk a mile in a poor person's shoes.
Poverty isn't about lack of money, is truly a cultural phenomenon. You need to erase every ounce of knowledge about nutrition in your brain. Get rid of your pots, pans, ovens, stove top, blenders, food processors, and toasters. Now work 16 hours a day and raise 3 kids on your own. If you're lucky enough to have a college education, you're paying a good chunk of your salary towards your loans. You don't have a car and most impoverished areas don't have a grocery store within a mile, so you're forced to grocery shop at 7-11. You basically easy out of cans and bags, because you don't have the equipment or time to cook. You don't have health insurance or internet because you're pinching every last penny. Most food pantries, if you're lucky enough to have one within walking distance or the bus line, only allow customers to be served twice a year.
These are the people I serve everyday. These stories are the norm, not the exception. Until you've experienced poverty, it's impossible to understand the importance of cultural capital. Have you ever actually applied for SNAP? When I was going through a rough time, I applied to see just how hard it was. Despite qualifying for the full amount, it took 11 months to receive my first benefits! They don't have a phone # or email so you have to keep taking days off work to show up at DSS and hope your caseworker is in. If he/she had the day off, they won't serve you and you've wasted a work day. It SUCKS.
Not every school has free/reduced lunch, and a good number of kids are toO embarrassed to accept it. I never attended a school that served meals, and honestly thought that was a regional thing
