Some facts, 1. UP, Bihar govts in past and present are not able to create good employment opportunities there due to it's own greedy politicians. 2. Due to no employment majority of UP and Bihar is uneducated and don't understand their own constitutional rights. They just come to metros to make more money. 3. Uneducation = No Civil Sense 4. People in metros don't like as these uneducated people behave as if they are still in UP/Bihar. They spit, are unhygenic, sit any where to do business(???), beg, borrow, steal. 5. Locals of metro are ignored as these people from UP/Bihar are willing to work at cheap rates. 6. Locals are pushed as they don't get jobs are are getting frustrated.
Result of all this? If you ask me I won't be surprised if sooner or later naxalite activities take control of Indian Metros.
