It's almost entirely a parenting issue... There are just as many rouge rich kids out there screwing up schools as their are working class poor kids... both lack basic home training and parenting (empathy, respect, motivation, emotional stability). Economics play a part to some degree in a parents' availability on both ends of the spectrum... but in the end it's the responsibility of the parent to raise their children - not the school system. Money don't fix bad non-existent parenting.... and Schools can't teach kids to be decent humans... nor should they be tasked with doing so.
