The economy of Maharashtra, as state is not very healthy in comparison to ther Indian States like Punjab,Gujarat,Karnataka etc. If the income of Mumbai is kept apart the state becomes as ordinary as Bihar.This is the reason why the people of Maharashtra are so possessive of Mumbai. In general the maharashtrian people are honest, straight forward, they have the image of arrogance and not hard working as Biharis or UPites,that's why the industrialist in Mumbai prefers other state people than Maharashtrian
This has become serious problem for Maharashtrians , they do not have the capital for the business like Gujjus/Marwaris/Parsis have, they are not professionaly qualified and not ready to face the competition like south Indians and some North Indians can take.
