Why don't the Marathi people speak in Marathi themselves?

This is the biggest problem which the language is facing now. I don't understand what is the problem with the Marathi Manus. Why doesn't the Marathi Manus speak in Marathi. Marathi has a history of 1200 years and is very prosperous language. However, when a Marathi Manus is supposed to talk with anyone on the street, he will always talk in Hindi. If it is an official situation, he will talk in English. Are they ashamed of their language.

Moreover, the Marathi youth is least concerned about anything regarding his language or state. I do not wish to criticize anybody, but I cannot stand anybody insulting my language and culture. If somebody is the culprit for that, I will surely mock him. Just because of some fools, I cannot allow my language to be insulted.

Don't you ever think that when you go to some other state, nobody there will speak in your mother tongue. The people with whom you speak in Hind are Hindi speakers. However, Marathi is not known in the entire country. Use Marathi, because if you don't, nobody will. Think that when you go to Tamil Nadu to work, nobody there will speak in Hindi let alone Marathi. Keep in mind that, when you respect yourself, only then do others respect you. So when you don't speak in Marathi, why will others speak in Marathi.
