To the sarcastic remarks that we should promote our kids to drop out of school...grow up. Obviously, you want to encourage your kids to go to school. Getting them to go to school has very little to do what with their future earning potential and everything to do with training them for whatever career they want to get into, as well as teaching them about commitment and hard work - also skills that you can develop in 'real life'. If your child's dream is to become a roofer, like uncle Ike, then he doesn't need to go to school. He needs to get into the workforce and get a job in roofing and learn about the business. Now, if his goal is to own and operate an empire of roofing companies, some business education couldn't hurt, but isn't required.
I know SO many University graduates that are serving people Big Macs now, so a degree does not equate to success...work ethic does. There was a girl that dated an old roommate of mine and she had a masters in Marine Biology, but was working at an ice cream shop, because she didn't want to move away from her parents. They live in Belleville...not a lot Marine Biology jobs there...so she will remain scooping ice cream until she sucks it up and decides to put the effort into her life.
I have a college diploma (in an unrelated field that I currently work in) and make more then almost everyone in my family. With the exception of the two lawyers, the doctor and the TV producer, I have the highest income of everyone in my family and most of the others have under and post graduate degrees. I am not quite at 100K yet, but will likely be in the next five years and I'm only 28. That being said, I have started taking part time university courses, to work toward a business degree, because it's a goal that I have.
Education is important, but not the true key to success.
