I agree with everything that foreverastudent said, but again, it comes back to taking some responsibility for planning out your own life. (not that I am suggesting that everyone will become CEO of a global company just by waiting until 30 to have a baby!)
I know that it is not feasible for everyone who is decent and well-intentioned to end up affluent or self-sufficient, for a million good reasons, and many will end up living in the horrible conditions she describes in spite of all their best efforts. They need constructive support, (but not patronising hand-outs for ever more with no expectations that they will aim to help themselves where possible).
It is sad that good but struggling people need to live around the squalour and anti-social behaviour created by others, just because they are poor. But we must remember who it is that is creating the squalour and indulging in the anti-social behaviour in the first place. We need a way of separating the 'deserving' and the 'undeserving' poor - but how? And at what point do we acknowledge that someone is only 'undeserving' i.e., feckless, lazy, criminal, or anti-social because they are a product of a dysfunctional hopeless environment? And how do we stop it without resorting to eugenics?
But we must acknowledge that many of those people who feel hopeless, helpless, trapped, would not be where they were had they not made poor choices at some point. It is well-intentioned but naive to think that all people living in disadvantage have just had 'bad luck' and that all affluent people have had 'good luck' though undoubtedly it is true for many. But we cannot outlaw 'luck' so we have to put it to one side and focus on what people make happen for themselves.
Many people who are trapped on benefits or in over-crowded poor quality housing are there because they have chosen to have more children than they can support, and to enter into parenthood when they are ill-equipped to do so, on a multitude of levels. Maybe without ever having had a day's work experience first. They have the well-intentioned but WRONG assumption that they can manage all alone in the world with no means of financial or emotional support, becuase if they love their babies enough, they can give them the world. They can't. What they can give them, sadly, is a one-way ticket to disadvantage.
People make bad choices by playing truant, fighting, laying in bed smoking weed all day, getting expelled, failing to do what is required to hold down the job the do have, etc, etc. Not all people, admittedly - but many. And if we toughened up on making people accept at least a degree of personal responsibility for their own outcomes and opportunites it would be a start. and less money spent on them would always mean more for the truly deserving.
