Infosys SEZ and present situation of information technology (IT Industry) in West Bengal

I wrote one article viz. "IT industry scenario in West Bengal -- gap between dream and reality" (http://avixorld.blogspot.in/2011/11/it-industry-scenario-in-west-bengal.html)  long back 2nd November 2011.
At that time TMC government just came to the power (approximately 6 month in realm) under the leadership of Mamta Banerjee who dislodged 34 years old Left Front Government.
After reading my blog one of my friend who is TMC supported told me that "My friend wait and see, there'll be revolutionary change!!"
Definitely I admit there is a change but the change flows towards negative direction!
My first thought in older post raised a concern about economy and now we can safely comment that in the mid of 2015 economy revamped, if not whole at least partially but investment in IT industry  of West Bengal has not been improved. Please note I'm not saying about the big Indian IT companies or MNC who're already doing their business in WB over last 10 years and it's expected that their head counts will increase naturally (as in all other IT cities in India) but more or less no new companies set up establishment has not been noticed in last 4 years of TMC regime.
My second point was about operational cost. According to the news published in all leading newspaper from Kolkata due to involvement of TMC leadership in Syndicate who supply cement and other raw building material has put a detrimental effect in increasing operational cost. A builder has  to buy the low quality of building material in the highest price. On the other hand the Syndicates pressurize to take the local party workers to give work in catering, security stuff , water supply etc. There is a security lapse for entering these kind of untrained and sometimes antisocial elements in IT Tech. Park and again you can't say anything to them as there is political influence and again due to higher price the overall operational cost increase. Consequently if the big fish e.g TCS, CTS still survive either sometimes by CM or Industry Minister intervention , the start up dare to think even set up an office.
My fourth point is invalid as due to no industry there is a surplus of power in WB!
And my last point is also doesn't have the major impact as here I like to give some marks in TMC lead Government who has improved little bit in transport. Again my view is not current , would appreciate if this assumption is wrong someone points me and I rectify!
Now about the recent SEZ issue.
It has been passed few years ago and only the last level of approval is pending from the Central Government part. TMC has got strong objection in SEZ but they never bother to mention the issues Surprisingly in the last Bengal Industrial Conference, when Amit Mitra , Minster of Industry and Finance , credited the TMC government about 20000 people to be recruited in TCS Rajarharhat which is a SEZ aka Special Economic Zone!
Infosys from the very beginning made itself clear that without SEZ they'll not set up the operational unit in Kolkata.
Then as a common man perspective one likes to know why Mr. Partha Chatterjee,Minster of Industry at that time came repeatedly to Bangalore and waste common tax payer's money. If from the very beginning TMC government opposes SEZ then neither Mr. Chatterjee should come in Bangalore rather at the very first onset TMC can say NO to Infosys,Wipro and other big software companies who're looking for SEZ.
Does it anyway improve the face of West Bengal?
People can see big buildings in Sector V remains vacant for 4/5 years whereas to get a building in prime location of Pune/Hyderabad or Bangalore is so difficult.
Probably name of West Bengal needs to be changed as Waste Bengal!
