free movement across the globe

In the larger interest it is extremely important to allow free and uninterrupted movement of people across the globe while taking the necessary precautions against criminals and terrorists.
Countries like USA,England,Canada and Australia prospered because they allowed immigrants from all parts of the world to work and settle.In the present scenario when the world is technologically inter-connected as never before it is a natural corollory that the world should become more homogenous and open.Due to air-travel across the globe,people are now meeting one another and exchanging ideas and cultures.English is fast becoming a common medium of communication across the globe.Unfortunately,today the afflunent countries are creating barriers between people .Such a situation will only lead to more tensions and discord in the world and nobody can remain immune from the resulting imbalances.
The techno-obsession of Western societies is only leading to frustration and violence within the societies and leading to problems like global warming and epidemics.Notions of nationalism and racism have no place in the modern world and a tolerant,open and pluralistic society will lead to prosperity and happiness for everyone.
