"if you go to a Georgia Public School you you have a much better chance of going to University of Georgia if you go to um a public school here in Tennessee you have a much easier chance getting into University of Tennessee in Knoxville... a lot of kids who go to private school the the public universities only allocate so many private slots from each of those schools so now you've got the all these kids competing and and that's the one I'm like so you paid all that money for Education only to make it harder"
