R1Geezer:
Please allow me to tell you about David and Lee. (Genuine names, genuine people. I used to teach both of them).
David joined our school, at the age of 14, because the school down the road had thrown him out and no other school would take him. He was the most naturally gifted mathematician that I have ever met (and I've known quite a few university professors). He was also incredibly 'personable'. (He had the ability to 'turn on the charm' in an instant. If I was his age I could easily see how I could have wanted David to be my best friend).
Unfortunately, David had terrible parents. For example, David left home to go to school on a Thursday morning, but he didn't turn up for school and didn't arrive home on Thursday evening. Most parents would have been panicking an hour or two after their son should have arrived home. David's parents didn't even bother to tell the police that he was missing until the following Monday!
David was also a 'rogue' and a thief. The police attributed the theft (or, more accurately, the 'twocking') of 14 different vehicles to David in a SINGLE NIGHT!
Lee, on the other hand, was one of the most delightful young people whom you could wish to meet. He was a delight to teach, hard-working, with regular attendance and wonderful, supportive parents.
However Lee, very briefly, fell under David's charismatic spell. (As I've said, I could see myself doing that if I'd been their age). David persuaded Lee to join him in an attempted burglary, where they both got caught by the police.
So now I have to consider your question as to whether throwing such families out of their homes would encourage better parenting.
I can't see that evicting David's family would have done anything to improve his (pathetic) parenting. (They'd have probably simply disowned him and left Social Services to 'pick up the pieces'). On the other hand, Lee already had 'near perfect' parents. (His actions left his parents stunned. They ensured that he was punished but, at the same time, they made sure that he knew that they still loved him and cared for him).
While I broadly support the right of local authorities to enforce their tenancy rules, I hope that what I've written might illustrate why I don't believe in simplistic solutions for achieving better parenting.
