People from UP and Bihar should be blamed for the current crisis. They have contributed a lot to development of our country in the past but I guess they have lost the way somewhere in between.
Most of the times they vote based on their caste and not for development. Hence they get leaders who are not capable of developing their states.
Also awareness about the education and health of children and women is below national average.
And I dont think anything more needs to be said about the goondagiri thats there.
All this turns away Industries and they need to go to other states for employment.
Considering the sheer amount of these migrants such clashes are bound to happen.
