The sad plight of north indians(people who live in up and bihar)can be attibuted to their bad management of their states. Infact, up and bihar are more fertile than anyother states and they also have natural resources. But the eole who ruled these states totally mismanaged for long period of time. They have not build educational institutions, they discouraged private investments and they always thought they are poor. Caste and religious differences played its role too. These north indians are more interested in their surnames. Everybody has got one behind their names and are proud to called by their surnames (castes) rather than names. Recently I met a coule in bangalore from north. After formal introductions, he asked my surname and he asked again and again and you all now southerners use their father name as their second name. I understood that they basically wnated to know my caste. This is thier mentality and it seems to be ingrained in their culture.
Now the time has come that these people are belted out from everywhere.
