> France, Germany, South Korea, Japan, and India all have enough unique, untranslated culture to get people to consider learning the languages that culture is written in
India is different from the other countries that had been mentioned. India is a union of many larger states. The government of India is actually called as Union Government in the constitution. India has 23 officially recognized languages https://en.wikipedia.org/wiki/Languages_of_India .
This summarizes. In India the union government is trying to push Hindi as the national language while the state governments are pushing back. This has been going for 70 years.
The interesting change is the due to jobs in south India north Indian state migrant workers moved to southern states. Their kids who go public school score higher in the native language classes than the native kids. This applies only for the low income migrant workers. The white collar job workers send their kids to private school and still learn Hindi.
In South India at least English is given more importance than the regional language.
PS: To those who are unaware of India, India has 23 officially recognized languages
