I am sure there is some collateral damage. I am willing to wager that you could find a few students who got the free food who actually did bring in money for the school system, but we look at statistics, not individual performance. Sort of like the teacher's union.
Everyday People Examiner: Cheese sandwiches for students whose parents are poor:
"The Albuquerque Public Schools system is not alone in their cheese sandwich lunch plan for children who do not have their lunch money. Reportedly, school districts in Chula Vista, California, Hillsborough County, Florida., and Lynnwood, Washington, have a 'cheese sandwich policy' in place."
Kids sure have a funny way of thinking. Somehow they seem to know who gets a free lunch and who doesn't, despite how professional the school personnel act in keeping student information protected. Just like kids know which kids are in the ESE classes. Maybe it's because ESE kids have different colored name tags, have a big sign on their bus that says "Alternative School", or even that little blue sign with the wheelchair on it. Kids just seem to know.
So, we have a group of kids eating together as a diversified unit, and the kids with the free lunch seem to have the most jewelry, most expensive clothes and the latest technology. The kids who pay for their lunch go home and tell their parents that they want this stuff too. After a few years of this, parents start to have a funny way of thinking, too.
