Dont worry too much, TN is developing very well in DMK rule infact it is doing much better in development than the previous regime. some examples
1) thousands of crores of investment in electonic manufacturing like dell, motorola, samsung etc 2) Chennai is maintainng its growth rate in software exports. Govt has signed numerous MOUs to develop Tidel park 2, and 3 and SEZs with Tata DLF etc.
3) even in automobiles new companies like Nissan , renault, Hyundai, Caparo are making huge investments in TN ( if you remeber most of the MNCs were running away from TN to Bangalore and Pune during prev regime).
On the infrastructure front, more and more state highways are coverted into 4 lane hwys. Sea water desalination plant that eluded TN during Jaya's govt is getting ready. New MOUs for powerplants are getting signed. Chennai Ennore and Tuticorin ports are expanded. Chennai Airport, trichy madurai airports are getting expanded and made into international ones. All the MG Rail tracks are getting converted to BG. MRTS got completed, Metro rail will be kicked off soon ( Jaya wanted monorail with much less capacity).
For southern TN, Tata titanium project was given impetus
I can go on and on and on like this. But I hate to sound like a DMK propoganda person. I hope you get my point... do u?
