School education especially higher education costs dearly but only makes a little profit. The expenditure in education is becoming heavier year by year for schoolchildren in big cities. Many parents feel the burden unbearable. A recent survey showed that the cost of college education had risen twenty times in the last ten years. So our country is among the most expensive in education in the world. In spite of the growing educational expenses, seeking employment has turned to be more and more difficult as the number of university graduates reached a record high. Their pay is lower than that of migrant workers. Most of them take jobs which have nothing to do with what they have learnt.
