All schools are not private , and so all schools do not work with the profit motive. Government schools themselves are not fully furnished or well designed, and i dont think they would have huge amount of funds with them. Also the teachers teaching in such schools do not have high pay and no pay during such pandemic would not be good to them. Indirectly, I suppose the schools with the nominal fee or lower fee structure can charge fees from the students but that to with some discount because parents too are burdened.
