It's not her shopping habits that are the issue. It's her disconnect. Trying to demonstrate hardship while spending, after cutting back, $12000 a year on food doesn't help her point. In fact, it decries her point.
The real problem is that people do not know how to handle the money in their pocket. As Bill Clinton said, the government could give you more, but "you'd probably waste it". No, the solution is for government to have more say in how money is spent. Specifically on food. Government control would cut our grocery bills, and help us to be healthier and less obese. Yay!
That's the ticket. Let's keep the focus on the silly consumer who spends too much!! Bad consumer! Bad! Bad! Bad!
