That 'darkest spot' regarding India's blighted state of primary-secondary education is directly Nehru's fault. In late '40s, India's first Fin-Min Mr S Chetty had proposed to increase literacy from 10% to 90% within ten years, and budgeted the the funds for same. That arrogant, elitist prig, the Idiot Nehru, nixxed the idea, saying India couldn't afford all those 'literates', preferring instead to create a couple of IITs to churn out the few highly educated technocrats who will overseer Congress govt's control over the 'commanding heights of the economy'. Everyone knows the results of his destructive Socialist policies - institutionalized corruption, red-tapism, rank poverty and eventual utterbankruptcy forcing the govt to go abegging to the IMF for a bailout loan in the early 90s - which demanded economic reforms as a condition for providing the meagre loan, on top of which, humiliated India by also demanding she deposit her gold reserves as collateral. Blight, Dark Spots.. thank Congress!
