very good analysis sajhamitra. but i chose to be different with your  demand supply calculation  . right now there is a high supply of college graduates dying to enter the job market but supply is only done by these fake consultancies with fake resumes in the IT market ( most of them). . so there is a monopoly in supply, being enjoyed by these fake companies because ppl with few years of  real experence or freshers don't stand a chance if they dont' lie.

if Demand is high , and if supply is not only limited to these companies then that would drive companies to  open more internship opportunies and vaccancies for freshers to learn  and be stable at the job.  that would open more opportuties for  F1 and real h1bs.  also , it is unethical and i'm pretty sure illegal too to say you're something that you're not. you can't practice medicine if you're not a doc or licensed practitioner. you can't drive commerical veichle if you don't have commercial driving  . what makes you ok to lie seven years of experiece and cheat . some managers may over look that fact because they can save money by hiring consulants than hiring someone with full benefits but thats unethical and illegal at the same time and no one suffers more than college grads with real degrees and dreams.

few years ago h1b system was on lottery system, there would be like 3 times more applications ont he day of h1b opening than the assigned quota. then USCIS started cracking down on these fake h1bs year there were less applicant than the quota , the quota was unused.   Now thanks to the crack down, h1b quatas are no issues lately. if they crack down more on the illegal and unethical  practice of thse companies and the greedy hiring managers at the client companies who pretend like they don't see anyting fishy  about someone bsing 7 years of experice then there will be more genuine opportunies for the new college grads and that includes our Nepali brothers and sisters to have stable jobs withouth consultancy slavery.
