Well I'm 19 years old and in university. I do work, but last year I only cleared about $20K. However:

-my car is totally paid off

-my parents bought me a condo to live in

-I have absolutely no school debt (in my 2nd year)

-and I basically live for free. I do have to pay my parents rent if I choose not to live with a roommate. I will have to pay some rent in the summer if I choose not to take summer classes, and I pay my own internet/cable (about $50/month). They pay for my insurance and my cell phone and will continue to while I'm in school (as long as I don't become too much of a fuckup).

Since I'm expecting to make $200K/year when I graduate university and the whole while in school I will be netting positive at the end of the year, I expect to become just as rich as my parents. I was able to do it by working like crazy in high school (I usually hit 40 hours a week at my healthcare job, although my parents really didn't like me working that much, so I cut my hours there I went and picked up a second job at a pet store) and starting working and saving really young (10 years old).

My parents are both extremely hard working and have instilled in me from very young that having a good work ethic is extremely important. So while I'm currently rich on their dollar, I do believe I will be able to pay them back 100% when I'm out of school. (They don't expect me to do that since they put away money for me and probably won't accept my cash, but I know I definitely want to do something special to show my appreciation when I graduate)
