Why did business owners favor few restrictions on immigration?
A
They were doing "community service."
Immigrant labor was cheaper than employing native-born
workers.
They believed that America should be a more diverse nation.
They were motivated by humanitarian impulses.

The correct answer is Immigrant labor was cheaper than employing native-born  workers.

Explanation:  It is easier for employers to find workers who are foreigners, as they are people who work in simple jobs and do not charge much, usually people who go to the United States have jobs that the Americans do not want so this makes it easier for employers who do not need pay a lot.

b) a state law could be declared illegal if it contradicted the constitution.

explanation:

the conflict of this case originated when james w. mcculloch, a cashier of the baltimore branch of the second bank of the united states that the congress had chartered in 1816, refused to pay a tax imposed by the maryland state.

in the case, the state of maryland appealed that the establishment of a second bank was unconstitutional since the constitution didn't say anything about granting that power to congress. however, the case determined that even if such right wasn't specifically stated in the constitution, it was part of the "implied powers" of the government enunciated in article i, section 8.

the case also eliminated maryland's legislation to impose taxes to a national bank, asserting that even though the states retained the power of taxation, the constitution's laws are supreme and can not be controlled by the states, therefore, if a state law contradicts the constitution, it should be declared illegal.
