Brainy Indians are piling into Western universities

OVER THE past two decades the number of people studying in countries other than their own has tripled, to more than 6m. International students from China have caused most of that increase. Youngsters flocked to universities in English-speaking countries to expand both their minds and their opportunities. In return they brought valuable brainpower and large piles of foreign cash. Governments have sometimes viewed this bounty as a reason to put less of their own money into higher education. Institutions in Australia, Britain and Canada have grown increasingly reliant on foreign flows to subsidise research and to cover the costs of educating local scholars.
