Upper class...probably no idea what a budget is. Do not pay their own bills..has an accountant to do that. Buy what they want when they see it. Travel at a whim. More than one car in the family. Post college educated.
Middle class...knows exactly how much money comes in and goes out every month. Budgets for everything. Possiblly college educated. Rarely masters degree
Just a couple more ideas for you presentation....godd luck keep us posted..interesting topic.
