Mallus typically go out of their states and exploit people in Tamil Nadu and North - they come back and invest in real-estate.
Bengalis, open up Dalmiya Cement factory and Square D Software Exports - (all bengali business guys are frauds btw) - in Tamil Nadu where they wont allow Red Flags!!!
Kick Mallus and Bengalis out of Tamil Nadu along with Gaulties. Tamil Nadu can shine without any of them.
