MBA.. is it mean or does it makes MEAN

U may know or u may not know, its a different story. But other person should only know that you know. Business stalwarts walking in the blazing suites have one thing in common (atleast most of them), all are Graduates in todays most sought after course.. MBA..But is MBA a Mean or does it makes us Mean.. In the pursue to earn big, are we caught inbetween the fine line of making it a mean or an end? Its an end for those who feel that it will take them to the Nirvana. But has anyone ever been able to attain Nirvana? If not then how can it be an end? Some people think that its a earning-multiplier. Yes it is. But then are they treating it as a Mean or ultimately making it mean?I would have a better personality.. Thats what everyone think before taking the course.. but later relaises that everyone else except him has changed.. because he is a big man now.. is his wallet inflating or his waist???Day and night one thought, 9L or 13L..work hard, thats what those old soul says.. but here they say, work smart..wasnt I smart enough to get here..so what am I doing??
