Karnataka had no problems even before the advent of IT. We had all comanies like: ITI, BEL, BHEL, BEML, HAL, ADA, ISRO. So economy and employment was not an issue.
AP has more population and that gets translated into higher IIT numbers.
Accept this fact buddy: A decade ago Hyderabad was in shambles. Every Telugu guy was looking for the first opportunity to sneak into Bangalore.
Even now Chennai is in shambles. Fishing, shipping were the major industries until recently. Bangalore was much better at all times.
If you really thing AP or TN is better then why dont you go back????
