Well, my thoughts are that you need to look at your own situation and make your own decisions, everyone has different priorities and are at different stages in their careers so no two reasons for a decision are the same. Also, it's common knowledge now that the US economy is an awful state and things are very hard for international students, things are just not the way it used to be and the clearer this is to an international student, I believe the better prepared he/she will be.
My personal opinion about an expensive MBA is this, if I had a good paying job with good prospects in the short to medium term , I wouldn't budge and burden myself with a huge loan. I'd rather weather this period out and then look for an MBA when returns (to an extend) can be guaranteed. Having said that, some people I have talked with have compulsions such as marriage, aging parents etc. Personally, I'm just beginning my career, I'd do no harm to my prospects with an MBA and I'm open to returning to India to work.
So, I'd say plan carefully, these are tricky times, if you've been a bit of a punter, you might take a punt in this situation, after all, in the long run an MBA will still pay off!
