the cost of private tuitions

i have written on the cost of education and the invasive and cancerous role of private tuitions.
rediff reports on an assocham survey - "Middle-class spends a third of income on kids' tuition".
as most of these students are inevitably in private schools, is it not a serious indictment of the private schooling system? i think it is.

maybe that is perhaps a bit narrow, the blame will have to be taken by all the concerned stakeholders, the apathetic schools, the harassed and anxious parents and the greedy shylockian coaching classes. and in this triple smorgasbord, the poor child gets whisked.
