<span>Because they thought that immigrants </span>would take occupations and jobs from Americans and they
additionally fear the foreigners would bring down the country way of life and
breed wrongdoing and infection in the US.
Immigration has been questionable in this nation as far back
as its beginning. At the core of the contention is fear. The genuine issue with
migrants is, and dependably has been, the dread that these foreigners will
overpower and undermine the lifestyle that makes America great. It is actually
an irony given the fact that the nation as it stands now is a nation of
immigrants :)
