How many of your kids have any idea what their phone bill is, or their computer or cable bill that allows them to order movies on demand without regard to the extra $6.99 that appears on your bill.
How will your teens ever develop an appreciation for what things cost unless you teach them. I am a big advocate whether you are a family of means or a family where you need to count every penny, that you have a monthly date to go over the bills. Let them see just how many movies they did order and what the cost was. How much their portion of their cell phone cost. Dollars and cents, they need the reality. So much of teens lives in this 21st century make it easy to live in lalaland. They can say things without consequence through impersonal devices, they can order things without using the old fashioned greenback, and so it is no surprise that when they go off to college with a car full of new clothes and comforters that it feels magical. They absolutely need to know that college can cost up to $50,000 a year, and that is a sh**load of money.
Start teaching them now. They may not have to pay the bills, but at least let them know that it all costs the real deal...money. Maybe there is a limit on downloads and uploads, and scanning the bills together you develop some budget items. Let them know that mediocrity is not acceptable for college when everyone in the family sacrifices for their ability to go. A little guilt never hurt! And more importantly, obstacle and challenge make the journey to success so much more meaningful.
