So at what age do your children outgrow the need for financial help? It may be older than you think. Recent research indicates that a whopping 93 percent of Americans who are a part of the baby boomer generation have provided some sort of financial help to their grown Gen X or Gen Y children.This is just to make you think. When does the Parent's Check Book Voucher expire? Are parents forever the go to people when things get tough? Would things even get tough if there was no parental open checkbook...do children get in a financial bind because they know the parents will help them out? You tell me.
