education ABROAD

Hi friends I need to discuss with you important topic students from developing countries going to developed countries to have their higher education. Is this correct? My opinion is no .The home country spends so much on ones primary level and elementary level education and we people go abroad for higher studies and forget about mother nation, We study our higher education there and get a job in that developed country and pay tax for that country this culture is mostly seen in countries like India, China, Pakistan etc .our country does so much for us but in return we have done nothing especially when lot of them need your help in your motherland. So friends think about it.
