So it's fine if I murder your family and take everything your children have so that my children can live in luxury?
In the US, mobsters kill with impunity while their family gets reality TV (Mob wives) showing off their life of luxury. The "children are innocent of their parents crimes" is unjust because the victims' children suffer.
The King is the child of a mobster. His luxury life came from violence. Your children will have to work their entire lives in part because of what the King's ancestors stole from them.
