The current bjp government is stealing the big investments/ projects that are meant for Maharashtra like the Foxconn and pressuring them to switch to GJ. In your own words, you mentioned developing underdeveloped regions. Why not the current government pressure investors to switch to Bihar or Jharkhand instead of Gujarat then. Further, How is this fair to other states when PM is favoring one state above all others and behaving like a "PM of Gujarat".
As for your "beat up" claim, Gujarathis are the people who discriminate a lot and play the "us" vs "them", so they cannot claim victim in anyway. Forget religious minorities getting discriminationed, even Marathis are discriminated in Maharashtra when it comes to housing as societies with lot of Gujarathis only consider other Gujjus. Go take a quick look at r/mumbai for instance
