I totally agree with what you're saying about inner city schools as till recently our DS was in one. Certain groups of parents were repeat offenders in taking extended trips to home countries. It had limited impact on those. Also the ones who didn't bother to bring kids in sometimes.
We home ed now and since we don't observe school holidays we educate all the time. It's a different dynamic and it makes you appreciate that a great deal of teaching time is probably lost in getting 30 kids organised whereas one in one you get quite a bit more done.
Me and my sister were taken out sometimes by my parents but both have good degrees and careers. A large part of this was down to parental attitude, discipline and aspiration. As regards some of the educational establishments I attended, I would say that in some cases I got an education in spite of them, not because of them. I had some inspirational teachers, but many were occupied in crowd control.
From my sons former teachers I always heard that the fines rarely changed the attitudes of the true persistent truants.
