I think a lot of it is that parents now, either young or old, are too lazy and selfish to go through the hard work of teaching kids right from wrong. It's easier to copitulate than stand your ground and often sacrifice something yourself in order to teach a kid what is right.
I think age of parents is almost used as an excuse to let some of them off, not just by them, but by the general public who see it as an easy explanation of their obvious failings, I also think that while having parents that work full time makes it harder it just means that extra effort needs to be pit in while they are at home, sadly, people aren't prepared to sacrifice their precious time to devote to their kids, and then who teaches them right from wrong?
My wife works with children and can see as early as three that they don't know how to play or amuse themselves as they are so used to being sat in front of the tv to keep them quiet, of they're like this at three what do people expect at 10?
Years ago I am told that everyone would be so concerned what the neighbours would think, that even if they didn't want to, the social pressure made th pit some effort in to parenting, now there is none of that and it's a loss to society.
I think until ther is a drastic change in society and what people expect from their leaders and government, each other, and moral values return to a more traditional way nothing will change. It will take a major event to effect this change, and I was hopeful it may have been the recession, however I don't think it'll be the case.
I'm only 26. I have a child of 1 and a child of 5, I work full time and my wife part time, yet we wanted kids and as a result will self scrifice to ensure they are brought up correctly, so I firmly beleive that all the excuses are just that.
Maybe it'll end up that parents need a licence before being allowed a child. I think it will be a sad day if it happens and promote all sorts of outcry but i can't dee another way.
