A modern child has more comfortable life than his parents had when they were in school...  I agree with this line as today's schools have modern facilities like clean drinking water, better washrooms, good furnitures and comfortable seats for sitting .. and they have smart classes , a computer lab , science lab , and many more national and international facilities ..cultural programs ,debate and speech competitions etc
But when our parents were studying they would not be having these facilities . like comfortable seats , they would not be having cultural programs ,clean water etc 
so we can say that today's children have better life than that of before 
Yes, we should agree because time changed. it is now modern,technology increased and new type of study began with many comforts.but in parents time their was no comforts
