Should We Pay Grade Schooler's for Good Grades?

I was listening to the radio on my way home from work, and a program similar to the NPR podcast embedded below came on and was discussed. I thought about it for a while and thought that it would be interesting topic to debate... Should we pay kids for getting good grades? Is it fair to only pay kids living in poverty for their good grades? Is this ethical?

There are many ideas and viewpoints on this topic, and I'm curious as to what you guys think about this topic, so listen to the segment below and tell proacktive what you think.

SIDEBAR: I'm going to try and find the radio show I listened to today as opposed to just this one because I liked the points that the person I was listening to today made better than what this program did...but nonetheless they are similar and bring up the roughly the same arguments...so stay tuned for when I update this post...
