Final answer:
The Irish suffered from denial of education and job opportunities, violence, and persecution in the United States due to widespread discrimination and prejudice against them.
Step-by-step explanation:
The Irish immigrants in the United States faced significant discrimination and hardship during the 19th and early 20th centuries. They were seen as an underclass compared to other groups, such as Anglo-Americans, and were often forced to take on menial jobs due to the widespread prejudice against them. The Irish were denied access to education and job opportunities, leaving them socially and economically disadvantaged. Furthermore, they were often subject to violence and persecution. Living in tight-knit communities, they were segregated from their Anglo neighbors, which only served to perpetuate the discrimination they faced. The discrimination against Irish immigrants was part of a broader pattern of ethnic prejudice that affected many groups, particularly newly arrived immigrants in America.
