Answer:
B.Companies in the U.S. outsource jobs to Ireland.
Step-by-step explanation:
Immigration is the act of moving from one's ancestral country to permanently live in a foreign country. During the industrial revolution in the United States, most people of Irish decent felt the need to migrate to the United States since there were more opportunities in terms of jobs. Ireland at the moment was rural and most of it's population was illiterate and lacking any formal skills.
The Irish mostly migrated to the United States to evade poverty and famine from their home country in search of better living and economic conditions in the United States. The United States were well into the industrial age with many industries and companies being set up. Since most Irish people did not have any formal training, they usually settled for menial work. The men always settled for labor intensive work that most of the middle class American citizens didn't want to do. The Irish work settled for domestic work. Both jobs did not pay very well.
Most Irish people during that time in history were very poor with most of them staying in low-cost housing and even streets. The locals despised them since wherever the Irish people stayed was occasioned by violence and overcrowding. A consequence of the poverty level among the Irish people. This was more prevalent during times when the U.S economy was not doing so well. The Irish immigrants were discriminated in many ways, such as; they were not allowed to live in certain areas of cities, they were denied work based on nationality since the Americans felt like they were taking their jobs and they were never allowed to hold public office.
During the civil war, the Irish people wholeheartedly participated in the war thus gaining some acceptance by the Americans. At this time, some of them had also moved up the social ladder thus gained access to live in certain areas of the city. Their populations had also increased with a majority of them getting into more professional jobs therefor could no longer be denied work based on their nationality. The increase in population also enabled them to elect their own to public office.
