You missed the other guys point, he was only trying to say the development in Mumbai has happened inspite of politicians. Now how Mumbai has developed and why Bihar & UP have not developed we can keep debating about that but will not lead to any worthwhile results. See people coming from UP/Bihar are coming there for livelihood, atleast they are not committing suicides as in Maharashtra and now you beat and threaten them to go back and hopefully commit suicide. And you say you have allowed Bhaiyas in Mumbai to do menial jobs, see India belongs to every Indian and I hope you are an Indian otherwise there is no point talking to you. Maharashtians also go to other places and maybe all over the world in search of greener pastures inspite of tremendous development (as per your views )would that stop. The same mentality was used successfully to garner votes spreading hate against south Indians not so long time ago. So think sensibly, if there are problems you should look for solutions beating poor taxi wallas and hawkers won't do any good.
