Final answer:
The immigrants have limited control over their own lives due to financial dependency and limited opportunities for financial independence.
Step-by-step explanation:
In the last stanza of the poem, the speaker suggests that the immigrants never had much control over their own lives. The immigrants experienced financial dependency due to borrowing money for their voyage and earning low wages, which limited their opportunities for financial independence. Although some immigrants were eventually able to escape the cycle of debt, most were trapped in ethnic enclaves and worked for wages instead of achieving their dreams. Therefore, the immigrants have limited control over their own lives.
