Yes I think he/she is suggesting sending your children to a 'crap' school to stop society becoming more divided. It's the best way to go about it that's why. A school cannot be inherently 'crap', it is the product of the teachers, pupils, parents etc that use it. If the majority of kids at a school are sent there with a healthy attitude and know how to behave that school will thrive no matter their ethnic or class background or whatever.
