Final answer:
Most of the Scots-Irish who came to the colonies were seeking better economic opportunities leaving behind economic hardship, while the Irish immigrants faced economic hardship and discrimination.
Step-by-step explanation:
Most of the Scots-Irish who came to the colonies were farm laborers or tenant farmers who were leaving behind economic hardship. They were seeking better economic opportunities in the colonies due to limited opportunities and poverty in their home countries.
The Irish immigrants, on the other hand, faced economic hardship and discrimination, especially after the Irish Potato Famine of 1845. They settled mainly in the cities of the East Coast and worked as laborers.
