shan,
in a previous era, usa was so open, that a visitor could walk into the plane to say 'good bye'. now they are paranoidly fearful of terrorism. and american flag carriers are the prime targets. it is unfortunate that many innocent muslims get tagged for extra security. incidently yours truly too, when i print out my boarding pass, gets the SSSS mark on the document - meaning i get special treatment. i just grin and bear it, and give myself extra 15 minutes, and am glad, in a way, that hopefully by this method, the real culprits are prevented too.
one has to agree, with all these security measures, we have not heard of any airline hijacking for the past several years. flying is now a privilege, and not a right, as it used to be previously
re everyone wanting to live in the usa: i live in canada, a fairly prosperous country. but even we used to be amazed at how easy a material life in the usa is. life, if you have a job, is indeed easy to procur. that country is going through rough times now, and not sure, how long it will be before it pulls itself through. it eventually will.
but appears to lack the political will at this moment. all because, வரவு எட்டணா செலவு பத்தணா being followed.
the usa has several hundreds of universities and many of them have post graduate departments. most americans, shun higher studies, as it is easier to get a job, and make money. the attitude in the usa re universities, afaik, is one goes to university only out of interest. otherwise ordinary folks can make a decent living working with their hands - plumber, electrician, carpentery - all are well paying professions.
indian & chinese students form the bulk of the post graduate students, because somehow or the other, they manage to get tuition waiver and work some part time work, and get a post graduate degree, and find a job in the usa. for most indian students, usa is an adventure, to be enjoyed, and also a period of growing up, away from their parents and restrictions. they mature, become self responsible and above all learn to wean themselves away from the parental money bag.
hope this explains, somewhat, why usa is such an attraction for indian students.
also, starting a business is very easy in the usa. the banks usually give money without bribes, and governments welcome businesses, because they provide jobs. profits is encouraged. unfortunately, some people took too much liberty and caused today's problems. but then that is another looooooooong story.
