I'm not sure the children would starve. As I already mentioned, we have the situation you describe tethersend atm, where in thousands of families on benefits the parents are alcoholics, drug addicts or gamblers, the DC don't eat regularly, and are not adequately clothed.
What has happened to those DC? Were the parents of those children given extra top up benefits, above and beyond what other parents with the same number of DC were given..because they had spent all the money on booze, gambling or drugs?? I don't think so.
How can you be so horrified that a child of a feckless parent who has not worked for a substantial amount of time is possibly going without food although I tend to think this would not happen regularly tbh yet are quite content to know that for years, alcoholics aand drug addicts have been encouraged to keep their DC living with them by SS and the govt, even while the DC have had their needs neglected.
Children are children to me, regardless of whether their parent is feckless or an alcoholic. Either we give them all enough money to make sure they can feed their children, or we don't. Why should the DC of gamblers, alcoholics and drug addicts go without adequate food and clothes because of the choices their parents make too?? Yet they have done for many years. Sad fact, but true.
