  Introduction India’s once-celebrated education system is under siege. Once seen as a gateway to social mobility, many private schools have now become profit engines—charging parents outrageous "donations" and forcing teachers into unjust working conditions. This article exposes the systemic exploitation in private schools, revealing the hidden costs that burden families and compromise the quality of education.
