I don't speak for all the rural areas, but jealousy is not the problem. It's the idea of having your cake and eating it too, then being so vocal as to your plight that you verbally attack anyone who says anything about it. As noted above by Gary's list, the percentages of private schools winning championships from 2000-2010 is disproportionate to the percentage of schools that exist in the state of Kansas.
What's wrong with saying because private schools have open boundaries and therefore they pull from a larger population than the public schools, that they should in some way be brought to a level playing field as the public schools. Choosing to pay a higher tuition is not in itself a leveler in competition. No, it's not jealousy, but it doesn't seem right.
