How is migrating to find work a cultural as well as an economic effect of imperialism?

Migrating to find work is a cultural as well as an economic effect of imperialism as the head of the family that migrates moves to a new place within the similar culture to earn for himself and the family but in order to earn more, he has to migrate to other places outside the circle of his culture.

Explanation:

In some instances, the work that is desired or the one that would fetch expected remuneration is not available at the place of residence. In such situations, there is no option left other than migrating to other places where the culture is different and the price paid for the skills that you bear is much higher. This kind of migration out of the cultural circle for the purpose of increased economic gains is referred to as an effect of imperialism.
