Consumers and producers obviously make decisions that mold the economy, but there is a third major element to consider the role of government. Government has a powerful effect on the economy in at least four ways:
Direct Services. The postal system, for example, is a federal system serving the entire nation, as is the large and complex military establishment. Conversely, the construction and maintenance of most highways is the responsibility of the individual states, and the public educational systems, despite a large funding role by the federal government, are primarily paid for by county or city governments. Police and fire protection and sanitation services are also the responsibilities of local government.
Regulation and Control. The government regulates and controls private enterprise in many ways, for the purpose of assuring that business serves the best interests of the people as a whole. Regulation is necessary in areas where private enterprise is granted
A. Postal system.

Immigrants are consumers as well as producers, so they create jobs as well as taking them. And the work they do need not be at the expense of native workers. Immigrants often hold jobs that natives are unwilling to accept at any feasible wage.
Also, immigrants sometimes help to keep industries viable (能存活的) that would otherwise disappear altogether, causing employment to fall. This was the conclusion of a study of the Los Angeles garment industry in the 1970s and 1980s. And when immigrants working for low wages do put downward pressure on natives’ wages, they may raise the (real) wages of natives in general by keeping prices lower than they otherwise would be.
In theory, then, the net effect of immigration on native wages is uncertain. Unfortunately, most of the empirical (经验主义的) research on whether immigrants make natives worse off in practice is also inconclusive except the effect, one way or the other, seems small. Most of this research has been done in A
A. they only take jobs created by immigrants
B. they often hold jobs that natives don’t accept
C. they do not put downward pressure on natives’ wages
D. they are unemployed most of the time
