eman, in theory you are absolutely right.
In real life (where most of us are sending our kids to Yeshiva) anyone trying to meet your standards will end up home schooling. Especially now that economic realities are not as rosy as they were a few years ago, the hanhalla is influenced by certain parents. And we all know who they are.
The most we can hope for is that the hanhala will not blatantly favor certain families, and that they will not allow them to have a say in specific matters of chinuch or halacha (e.g. zmanim of tefillos, which masechta to cover, tznius standards).
