Why did the new immigrants deal with more problems than earlier immigrants

Why did the new immigrants deal with more problems than earlier immigrants- The United States experienced major waves of immigration during the colonial era, the first part of the 19th century and from the 1880's to 1920. Many immigrants came to America seeking greater economic opportunity, while some, such as the Pilgrims in the early 1600's, arrived in search of religious freedom. From the 17th to 19th centuries, hundreds of thousands of African slaves came to America against their will. The first significant federal legislation restricting immigration was the 1882 Chinese Exclusion Act. Individual states regulated immigration prior to the 1892 opening of Ellis Island, the country’s first federal immigration station. New laws in 1965 ended the quota system that favored European immigrants, and today, the majority of the country’s immigrants hail from Asia and Latin America.

the transatlantic slave trade radically impaired africa's potential to develop economically and maintain its social and political stability. the arrival of europeans on the west african coast and their establishment of slave ports in various parts of the continent triggered a continuous process of exploitation of africa's human resources, labor, and commodities. this exploitative commerce influenced the african political and religious aristocracies, the warrior classes and the biracial elite, who made small gains from the slave trade, to participate in the oppression of their own people. the europeans, on the other hand, greatly benefited from the atlantic trade, since it allowed them to amass the raw materials that fed the industrial revolution to the detriment of african societies whose capacity to transform their modes of production into a viable entrepreneurial economy was severely halted.
