They should have to pay more than the average salary. Assuming they have equal abilities, a local worker should be preferred over a foreign worker. That kind of social contract encourages locals to invest in education because they know they won't have to compete against a global workforce. IMO it's not a good idea to increase dependence on foreign workers and, in turn, foreign education systems.
