Medical seats and black money!

Do you hear or see the Ads for  seats in AIIMS or IITs ?
Never. but you  can see the Ads in the media in full galore for guaranteed  MBBS seats in colleges across the country.
Why its happening in medical education especially in private sector ?

 Is it fueled by black money? Is it due to complacence on the part of govt?
Is it due to exploitation of indian middle class mentality by the burgeoning private medical college managements?

Yes,
Behind this promise is a black market in medical seats in private colleges. With agents and college managements colluding to sell many of the 30,000-plus MBBS and over 9,600 postgraduation seats in private medical colleges, back-of-the-envelope calculations by TOI suggests that about Rs 12,000 crore in hard cash changes hands in this black market every year.

Of the 422 medical colleges in India, 224 are private, accounting for 53% of MBBS seats. Many of these colleges are running with little or no facilities, no patients and fake faculty. The going price for an MBBS seat could range from Rs 1 crore in colleges in Bangalore to Rs 25-35 lakh in some in UP. Seats in MD in radiology and dermatology cost up to Rs 3 crore.

While the 15% NRI quota seats are allowed to be allotted at the management's discretion in most states, in reality, even the management quota and a chunk of the so-called merit seats are sold off, bringing the proportion of seats sold to over 50%,
The bulk of the money is paid in cash, leaving no trace of the transaction. And despite the advertisements giving the game away, the government has not cracked down on this black market or taken steps to arrest the rot in the medical education system.
why?
Is it because,as govt is not in a position to establish medical colleges and so it is bound to encourage such type of illicit transactions to sustain the private medical education owners?
or is it due to lazy corruptive complacent system?
