Extremely naiive view I think. Where is the evidence of the cross section of labour supporters. And I think its bordering idiotic to think that there is a huge number of parents whose kids wreak havoc on the streets, this group is in a minority. Granted a family/couples should look at the costs of having a child, but it shouldnt be the deciding factor in having a child. Most children are born out of love, not as a gift to themselves which they can afford. I find it ludicrous that you think that every working class family has kids who wreak havoc on the streets. That opinion you express, suggests that you have an extremely narrow mind. Try and branch out, dont make sweeping statments about a social class that you obviously arent a part of.
*edit* grammar
