The fastest growing economy in the world would not be possible without the sweat and muscle of migrant workers. Just as in all major cities in China, Beijing requires a large amount of manpower to complete all the necessary construction. With the additional manpower comes the extraordinary task of housing, feeding, and accommodating the incoming masses of migrant workers. Because of high fees charged by public schools, this 'mobile' population has no other choice than to send their kids to the cheaper so-called 'Migrant schools' which are understaffed, ill-equipped and offer a low-quality level of education.
