It is not wrong to transfer wealth to your children, but they should be taught to value and preserve it.
When it was wrong? 
I've seen many people are complaining how the life of someone else looks easier because their parents provide everything, unlike their own parents. That's what supposed to be, the parents work hard to fulfill their children needs, why they have to give it for free to other children?
It's unfair, but we have a choice, do we want to stuck forever and life like this? or we take a move and improve our life the maximum we can?
