Why not Privatization of Indian Secondary Education?

Comparing with the likes of developed nations on the ground of education still makes me feel more uncomfortable than in any other field. At the grass root level of indian education, which is wide-spread across the country and having the maximum penetration into the society (am talking of Govt. schools and specially the secondary schools).
Each year hundreds of thousand young graduates are recruited into this system and each one is more qualified than the next one( thanks to our unemployment figures that forces a master degree graduate to be a primary school teacher). But when it comes to service life they are more centred to their prosperity rather to the prosperity of education for which they are paid. Education Bureaucracy is very much responsible but why to blame always others even if we itself desires to work less and to be paid heavily. Almost 60% of teachers of secondary schools become useless after a decade becoz their knowledge reduces to almost 20% and thats too much obscure to present needs. And this is contributed by their behavior of teaching less and earning more & more. If a contractor reaches a teacher to make him earn in lieu of some clients to be arranged by the teacher, he will be more interested in getting details but when a student comes to him having some difficulty he shouted and mistreated him for his ignorance. Here i don't know whether he is shouting at student's ignorance or his own.
Recently, i come to one such great soul and when i explained all these to him, expecting some explaination from him. And what he explained to me is that Western culture is rotting our young generation, they don't know how to behave in public. Well, nothing i colud to his thinking but atleast i can learn from these.
