Yeah, it's the easiest way to discriminate against poor people without getting into trouble. Hell, you can even point to papers that say parental participation in schools helps the children. All the while you know poor folks won't apply.

Am I understanding correctly that this is in fact literally the same issue as the voter registration problem in the US? (or was it the voting booths. anyway, the problem of being too far away and during "working hours" strongly selecting against the underclass)

Same thing right? There's a large underclass in the US that simply cannot take part in public society activities because they are indentured?
