In other side, It is really painful to see that why people are migrating towards metropolitan by leaving their families and favourite memories at their natives. In my experience, I have seen migrants to be enjoyed for some initial days at metros, but sooner they get bored and like to go back to their native. This applies to people who have migrated to abroad also. But, they are not able to go back to their native because of changed lifestyle and their needed money is available only at metros.
We may think that people who migrate from rural to urban to get richer life are selfish. They don't thought to improve the class of rural by working there and pulling people there. They haven't taken a fair decision to live with whatever available in rural. Though these sentiments may seem good to think, it is not at all possible for "majority" of people to live with these thoughts. I feel that it is not advisable to keep our young talented world-class people to work on local tasks alone selfishly. This is age for them to take calculated risks and try out new experiments. They want more challenges in life that are available in abundance in our metropolitans. Also we are living in global era where migration of rural to urban / urban to metros becomes inevitable.
The solution for this problem shall be improvement of rural infrastructure to world class. It should help our talented young world-class people to work globally by sitting rurally. They should be able to start new ventures and compete globally. While reading this post, if you feel that this is a well-known problem with well-known un-realistic solution, you are wrong. Let me walk you through one of the sucess story to understand how to work rurally and compete globally.
Mr.Nagarajan from usillamptti (a small town near Madurai) has come up with a grassroot innovation called garlic peeler to peel-out dry garlic skins. This device as you see in the below picture peel-out garlic skins within minutes.

NIF(National Innovation Foundation) has recognized Nagarajan's Innovation. NIF helped to protect this innovation by IP (Intellectual Property) rights and helping him to market globally. When chatting with him, he mentioned that he devised this to ease garlic pickle preparation but companies are finding many applications out of this device. He has sold this device to many great Indian companies. He casually said that he has approached all major Indian players and aggresively targetting global markets. He also proudly mentioned his device will peel-out skins of all types of garlics compared to similar foreign devices that would peel-out their local garlic species only. He has internet in his office room and check mails. Wow! This is good successful model to work rurally and compete globally.
