Everyone know about that, but the reality there are still a lot young people become gambler or end up in other addictions. That's because the parents don't have much time to teach and control their children, most parents choose to work because they think money is the most important, so they leave their children to babysitters.
Babysitters don't care with your children, all they do is fulfill their job desk, that's all. They won't give more effort or special treatment like their' own children.
Parents aren't wrong in thinking that money is important because it's true, we live in a world where you can do nothing at all if you don't have money. However, good parents would find a way around it, which means that one parent would work and the other would stay at home with children, and the staying at home part is usually the mother's responsibility, or in most societies, women take care of the home and the men go out and work to earn a living for the family.
So what's important for parents is to make sure that their children's upbringing isn't disturbed because of their irresponsibility, while it's important to earn money, it's their duty to make sure that at least one parent stays around the children at all times.
