What is your mother tounge? The mother tounge influence is a problem when speaking in English in India. If my experience is anything to go by, it's not a major problem when speaking in Indian languages.
As far as your claim that people in France, etc using their own mother tounge, they were not subjected to foreign rule for hundreds of years by the English. Has not the Persian language, which was alien to India before the Moghuls, influnced Hindi language? For a person whose forefathers migrated from Tamil Nadu to Karnataka, which is the mother tounge? Tamil that is spoken at home (which he does not know how to read or write) or Kannada (which he studies in till 11year old), or Hindi (the national language, studied as a compulsory language), or English in which he has studied all subjects from the age of 11?
The countries that you have mentioned developed scientifically and industrially without the help of the English; also, they do not have so many "mother tounges" in their countries.
Have a nice day.
