Indeed, Bihar is one of the most backward states in India where more than 50% people are uneducated. Only 15% of people reach high school. Often student migrant to other states for the better education. The situation of Bihar was not like that at the time of Independence. However, due to worst politics, caste system and fewer opportunities of job/work made the status of Bihar something that even a person who does not know the ground reality of this state, pass a half-baked judgment to the entire people of the state. This is the actual reality that even if they do good work or do the highest level of government job, they will never be entitled to the basic respect. Sadly, even people from the different state who call themselves "educated" take no time to vent out their hatred feeling toward Bihar or Biharis.
However, even being in this poor situation, student those who are good at studies, do their hard work and go for Government Job. Because there are no opportunities on private firm/companies, so they have only option to go for the Government Job. That is why those brilliant students work hard, go for competition exams, if not they go for the Police or Army job.
I know and have seen how student under shortage of everything work hard and gets the Government job. Yes, cheating is there, there is no denying on it. But, saying the entire students are the cheater, is something we should think 100 times before making a comment, think of those difficulties of the student in which they are in and then pass your judgment. Just because your daughter or son is a hard worker on studies does not give anyone the right to comment "cheater" to the entire Bihar state.
I would certainly say that it is the Biharis who have to think over than politics and caste system to bring out themselves from this poor situations. Moreover, uneducated people are the main problem who does not understand the bad politics and dance with politicians tune.
In the end, I will only say that though Bihar and Biharis have the shortage of everything but Strong Brain. If they are not better to compare to other state people, they are not lesser too. It is just the time and situation and they have shown their worth on every international level.
So, don't judge Biharis with your personal opinion.
