"use their children as vehicles for their own happiness"
"One thing that means is that children and parents depend on each other more for happiness. It puts a burden on children for parents to use their children as vehicles for their own happiness - although today's young people seem complicit in this arrangement, perhaps because they've known no other way - even if it creates anxiety in the children."
Does "young people" refer to "children"?
If that is the case , are these sentences mean that, parents put children as their own happiness and children are also willing to be it, even though this puts a burden or creates anxiety in the children?
