Raj Thakray has stirred a big contravery by making very bold statements. He may not be wrong on the questions he raised but his this may not be appropriate solution as well. If you ask any marathi bloke in Bombay, he'll support Raj's opinion in private, but will more than hesitate to go public.
The reality is, Mumbai is flooded with non locals, some coming here 30-40 years ago and some more recently. Now, that was not a problem as long as locals had enough oppportunities and enough to live their lives peacefully. Things have changed with changing times and that's resulted in a disparity of weather and status of locals vs non-locals. In Mumbai, the local marathi people have been virtually driven out of their dens in Girgaon, Parel, Dadar and ended up in distant suburbs of Kalyan, Ambarnath, Virar, Dahisar and so on. Jobs are a scarce commidity and competing with masses has made life more difficult.
This's the problem everywhere, all prospering cities and state go thru' this cycle. Be in Bangalore or Delhi or the USA. e.g. Desis in USA are very much like Bhaiyas or Biharis in Mumbai. They work hard,4-5 live in an apartment, take away jobs from locals and are willing to do whatever it takes. They see the life getting only better in the foreign place.
Why blame outsiders if you can't compete? These are times of opportunities, and fittest will survive making most of these opportunities.
