That is the entire point of this immigration, as Samir Amin states:

Successive waves of immigration also played a role in reinforcing American ideology. The immigrants were certainly not responsible for the poverty and oppression that lay behind their departure for the United States. But their emigration led them to give up collective struggle to change the shared conditions of their classes or groups in their native countries, and adopt instead the ideology of individual success in their adopted home.

Adopting such an ideology delayed the acquisition of class consciousness. Once it began to mature, this developing consciousness had to face a new wave of immigrants, resulting in renewed failure to achieve the requisite political consciousness. Simultaneously, this immigration encouraged the “communitarianization” of U.S. society. “Individual success” does not exclude inclusion in a community of origin, without which individual isolation might become insupportable. The reinforcement of this dimension of identity—which the U.S. system reclaims and encourages—is done to the detriment of class consciousness and the forming of citizens.

Communitarian ideologies cannot be a substitute for the absence of a socialist ideology in the working class. This is true even of the most radical of them, that of the black community.
