We dont have to chase away tamils from karnataka. The high cost of living itself has done it. People can run a family peacefully in tamil nadu I understand with just few thousand rupees so all tamils have left karnatak and this has been replaced by all north indians from various parts of bihar, UP, MP and Rajasthan. Whitefield , marathahalli, KR Puram and kadugodi is just filled with people from Bengal and northern India. Ragava
