mumbai is mumbai! Politically it may be part of Maharastra,culturely its never a part of Maharastra.Its a metropolis,its a part of cosmopolitian India where it doesnt matter marathi or a bihari,all that matter is u r indian national,even in some cases thats too doesnt matter if u talented in ur own fiel e,g Adnan Sami the singer from Pakistan.Most companys,banks HQ are in Mumbai not bcoz of Maharastra state, they r their bcoz they want to be in mumbai.Its high time marathis get this clear out in their mind that Mumbai is Mumbai bcoz of marathis.Its mumbai only bcoz of its cosmopolitism.
