It should be mentioned that currently 40% of Indian children are enrolled in private ("independent") schools, which in turn make up 25% of the K-12 schools in India[1]. The public school system is viewed as such a poor education that demand for private schools is high, and thus can be quite affordable too; as low as $2 per month[2]. Which even in India is within the reach of most families (minimum wage there is ~$225/month).
