I think that teaching your children how to make money while they are still young is one of the most valuable things you can do for them. This, along with the ability to learn independently, will allow them to avoid a lot of misery for the rest of their lives.
There are many people who are doomed to stressful lives living paycheck to paycheck because early in life they didn't learn a lucrative trade and they didn't learn how to learn. Once you are out of school and have a job and maybe a family, just the day-to-day demands of living can drain most of your energy and time.
