School children are very low in the social hierarchy, of course, because they cannot defend themselves. Of course they are going to be oppressed when they note that there's no system behind and when they say it's too complicated they will be called lazy. The parents had to wade to shit, so they don't even notice the smell anymore, and now the children have to, too.
On the other hand, conservative orthography can help to learn the related languages (ie. French, Latin), serve as interesting step into history, exercise memory, and what not.
There could be no regular spelling. That's an illusory proposition, given the breadth of dialects that exist. So next you will require all the poor children to learn a new dialect, basically. Is that any better? It would be a loss of diversity, each one preserving a little bit of historic language development - and status. It's really a shame that status varies. Learning a language properly might give some stability.
