I'm moved by the empathy that some of you have. :

You see a snapshot of someones life and are in a position to make judgements about them.
These people needed help to put them on the right track, they obviously didn't get it and sadly didn't have the skills needed themselves nor did they get them from their parents.
Thankfully the 'posh' couple have a greater sense of humanity and social awareness than some on here. They put aside their initial prejudices and seem to have a plan on how they could help and actually make a difference. It starts with educating them on family life, giving them a sense of purpose and inclusion. When society starts to do this change is possible. When they simply whinge about them, apart from making the whinger sound superior, nothing is accomplished.
Compared to some many of us have had a very easy start to life with parents who were able to socially educate us and give us a sense of worth and a good work ethic. Not everybody gets that. This couple clearly didn't. Hopefully with the help they recieve the next generation will move on and make something of themselves.
Thank goodness the 'posh' couple were prepared to help.
